Correct Answer
A. Mouse
Explanation
The part that controls the cursor is the mouse. The mouse is a peripheral device that allows the user to move the cursor on the screen and interact with graphical user interfaces. It typically has buttons that can be clicked to perform various actions. The keyboard is used for inputting text and commands, the monitor displays the visual output, and the motherboard is the main circuit board of the computer. None of these options directly control the cursor like the mouse does.

These parts are necessary to allow sound to come from the computer
Correct Answer
B. Speakers and audio cards
Explanation
Speakers and audio cards are necessary to allow sound to come from the computer. Speakers are the output device that converts electrical signals into audible sound, while audio cards, also known as sound cards, are responsible for processing and transmitting audio signals to the speakers. Without both of these components, the computer would not be able to produce sound. Headphones and video cards are not directly involved in the production of sound, and an audio card alone would not be sufficient to produce sound without the presence of speakers. Therefore, the correct answer is speakers and audio cards.
