Explanation

BIOS firmware is stored on an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip, which can be rewritten electronically - a process called 'flashing.' This allows manufacturers and users to update the BIOS without physically replacing the chip. The Northbridge controller (A) is a chipset component that manages communication between the CPU, RAM, and PCIe - it does not store BIOS. VRAM (B) is video memory on a graphics card. The CMOS battery (D) powers a small CMOS chip that stores BIOS configuration settings (date, time, boot order) while the PC is off - but the BIOS code itself resides on the EEPROM, not the CMOS chip.
