Answer:

Hard Disk

Explanation:

A very important part of a computer is the hard disk. It stores data and documents that users may have downloaded. Removing the hard disk could make the computer useless.

A mouse, keyboard, or pen drive can be easily removed.

A mouse and a pen drive are USB-connected devices and can be removed by simply unplugging the cable. A keyboard can be removed by simply taking off the keycaps. It is easily accessible.

The person above me is correct. The answer is hard disk. A mouse and keyboard are both plugged in and will not affect the computer. A pen drive is just a flash drive which is also removable. However the hard disk can not be removed but has similar capabilities as a pen drive via storing memory.
