Which memory retains its instructions even when power is turned off?

Answer and explanation

Correct answer: ROM

The governing concept is non-volatile memory. ROM retains its stored instructions even when the computer is switched off, so it can hold firmware or boot instructions needed during startup. Cache memory, registers, and RAM are volatile working memories whose contents normally disappear when power is removed. ROM is not intended for rapidly changing temporary data, but its ability to preserve instructions makes option C correct.
