What is the correct association between a hardware component and a computer function?

Let's understand the options:

Option A: Monitor > input
A monitor is what you see; it displays information. It doesn't take input; you use other things like a keyboard or mouse for that. So, this is incorrect.

Option B: Mouse > input
A mouse lets you control the cursor on the screen and click things. This is how you give instructions to the computer, making it an input device. This is correct.

Option C: CPU > storage
The CPU (Central Processing Unit) is the brain of the computer. It processes information, not stores it. Storage is the job of things like the hard drive or RAM. This is incorrect.

Option D: Hard disk > processing
A hard disk is where your files and programs are saved. It's storage, not the part that does the processing. The CPU does the processing. This is incorrect.

Option E: None of these
Since Option B is correct, this is incorrect.

Therefore, the correct answer is B: Mouse > input
