Device that reads from and writes to a disk.
Correct Answer
B. Disk Drive
Explanation
A disk drive is a device that reads from and writes to a disk. It is responsible for storing and retrieving data on a disk, such as a hard disk or a floppy disk. This device is commonly used in computers and other electronic devices to provide non-volatile storage. Unlike memory, which is volatile and loses data when power is lost, a disk drive retains data even when the power is turned off. Therefore, a disk drive is the correct answer as it specifically performs the task of reading from and writing to a disk.
