B Correct answer
Explanation

BIOS firmware is stored in ROM (Read-Only Memory) chips on the motherboard, specifically in EEPROM or flash memory. ROM is non-volatile and retains its contents without power, unlike RAM which is volatile. The CPU executes BIOS code but doesn't store it. The hard drive stores the OS and applications, not the BIOS itself. ROM ensures BIOS is available immediately upon power-on for the boot process.
