___________________rice is healthier than white rice.
- A.
  
  Black
- B.
  
  Brown
- C.
  
  Yellow
Correct Answer
B. Brown

Explanation
Brown rice is healthier than white rice because it undergoes less processing and retains more of its natural nutrients. Unlike white rice, which has had the bran and germ removed, brown rice still contains these nutrient-rich components. The bran and germ contain fiber, vitamins, minerals, and antioxidants that are beneficial for overall health. Additionally, brown rice has a lower glycemic index, meaning it causes a slower rise in blood sugar levels compared to white rice. This makes it a better option for managing blood sugar levels and reducing the risk of diabetes.

Flowers and plants do not produce the type of hair or fur required to manufacture woolen clothes.
