Sunflower is an oil yielding plant because it produces seeds that are rich in oil content. These seeds are commonly used to extract sunflower oil, which is widely used for cooking and in various food products. Sunflower oil is known for its high levels of unsaturated fats, vitamin E, and other beneficial compounds, making it a popular choice in the culinary industry and for its health benefits.

Animal husbandry is the correct answer because it specifically refers to the branch of agriculture that deals with the raising and care of animals for various purposes such as meat, milk, eggs, and other products. This includes tasks like day-to-day care, selective breeding, and managing livestock.

Manures can be classified into two types based on the kind of biological material used. This means that there are only two categories or classifications of manures based on the type of biological material they are made from.

Using fertilizers in farming is considered a high cost production method because fertilizers can be expensive to purchase and apply. Fertilizers are used to provide essential nutrients to crops, which can result in increased yields and improved quality of produce. However, the cost of fertilizers, along with the equipment and labor required for their application, can significantly impact the overall production cost for farmers. Therefore, using fertilizers in farming is an example of high cost production.

Nickel is considered a micronutrient because it is essential for the growth and development of plants. Although it is required in very small amounts, nickel plays a crucial role in various enzymatic reactions and metabolic processes in plants. It is involved in nitrogen metabolism, DNA synthesis, and the activation of certain enzymes. Therefore, even though nickel is needed in trace amounts, it is still classified as a micronutrient due to its importance in plant physiology.

To solve the food problem of our country, all of the options mentioned are necessary. Increased production and storage of food grains will ensure a sufficient supply to meet the demand. Easy access to food grains for people means that they can easily obtain the necessary food. Lastly, people having money to purchase the grains is crucial as it allows them to afford the food and maintain food security. Therefore, all three factors are essential in addressing the food problem in the country.

The correct answer is Sulphur. The other options, Boron, Zinc, and Chlorine, are all micronutrients required in small amounts by plants for their growth and development. Sulphur, on the other hand, is a macronutrient needed in larger quantities by plants for various physiological processes such as protein synthesis and enzyme activation. Therefore, Sulphur is the odd one out among the given options.

Catlas is a type of fish that is known to be a surface feeder. This means that it primarily feeds on food sources that are found near the water's surface. Unlike some other fish species, Catlas does not typically dive deep into the water to find its food. Instead, it prefers to stay near the surface and feed on insects, small crustaceans, and other organisms that are easily accessible in that area. This feeding behavior is characteristic of Catlas and sets it apart from other fish species like Rohus, Mrigals, and Common carps.

Maize is a Kharif crop because it is sown in the rainy season and harvested in the autumn. Kharif crops are typically grown during the monsoon season in India, which lasts from June to September. Maize requires a lot of water for its growth, making it suitable for cultivation during the rainy season. Wheat, Pea, and Mustard, on the other hand, are Rabi crops, which are sown in winter and harvested in spring.

Plants obtain various nutrients from the soil, and 13 of these nutrients constitute approximately 0.5-6% of the plant body.

Snapdragon does not belong to the group of short day plants. Short day plants require a specific period of darkness to initiate flowering, while Snapdragon is actually a long day plant. Long day plants require a certain minimum period of daylight to trigger flowering. Therefore, the correct answer is False.

Chemical fertilizers are not broadly classified into three types. They are typically classified into two types: macronutrients and micronutrients. Macronutrients include nitrogen, phosphorus, and potassium, while micronutrients include elements like iron, zinc, and manganese. Therefore, the statement that chemical fertilizers are broadly classified into three types is incorrect.

Plants require 17 nutrients for their growth and development. These nutrients include macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients like iron, zinc, and manganese. Each of these nutrients plays a crucial role in various physiological processes of plants, such as photosynthesis, root development, and overall plant health. Therefore, the correct answer is 17.

The given answer, 18, indicates that currently, 18% of all cultivable land in the country has assured irrigation. This means that a significant portion of the land used for cultivation is provided with a reliable water source, ensuring that crops can be adequately watered and grown.

An apiary is a place where bees are kept and raised for the production of honey and other bee products. It is a specific location where beekeepers maintain their beehives. The term "apiaries" is used to refer to bee farms because it encompasses the entire operation of beekeeping, including the management of colonies, collection of honey, and the overall care and maintenance of bees.
