A CD-RW disk

AHas faster access than other disks

BIs a type of magnetic disk

CCan be written only once

DCan be erased and rewritten ✓ Correct

Correct answer: (D) Can be erased and rewritten

Explanation

A CD-RW disc can be erased and rewritten many times, giving reusable optical storage.

It does not have faster access than other disks, that is not its defining trait.

It is an optical disc read by laser, not a magnetic disk.

Being writable only once describes a CD-R, not a CD-RW.

The RW label itself stands for rewritable.

Its recording layer changes state under laser heat to store or clear data.
