A ....... is hardware used to read disks.
Explanation:
The correct option is (D) disk drive. A disk drive is a hardware component designed to read data from and, in many cases, write data to various types of storage disks. Examples include floppy disk drives, CD-ROM drives, DVD drives, and Blu-ray drives. These drives contain the mechanisms necessary to spin the disk and use lasers or magnetic heads to access the stored information. Option (A) a floppy disk is the storage medium itself, not the device that reads it. Options (B) hardware and (C) software are too general; hardware refers to all physical components, and software refers to programs. Option (E) CPU (Central Processing Unit) is the main processor of the computer; it processes data but does not directly read disks; it relies on the disk drive to provide the data.
