B Correct answer
Explanation

ROM (Read-Only Memory) is non-volatile memory that retains its contents even when power is turned off. Unlike RAM, DRAM, and DIMM which are volatile memory types that lose data when power is removed, ROM stores permanent instructions like firmware. The CPU is a processing unit, not storage.
