(d) ROM (read only memory)

I had been asked this question during a job interview.

This interesting question is from Protected Virtual Address Mode (PVAM) -2 in division 80286-80287-A Microprocessor with Memory Management and Protection of Microprocessor

Answer 1

Correct answer is (c) cache memory

To elaborate: To minimize the time required for fetching the frequently required descriptor information, from the main memory, cache memory is used in which the most frequently required data for execution is stored.
