B Correct answer
Explanation

BIOS (Basic Input/Output System) firmware is stored in ROM (Read-Only Memory) chips on the motherboard. ROM is non-volatile memory that retains its contents without power and cannot be easily modified. RAM (A) is volatile memory cleared when power is lost. The CPU (C) is the processor that executes instructions. The hard drive (D) stores software and data, not the BIOS firmware itself.
