Why each option
The BIOS is firmware stored on a non-volatile ROM or flash chip soldered directly onto the motherboard.
RAM is volatile memory that loses its contents when power is removed; the BIOS must persist without power and therefore cannot reside in RAM.
The hard drive stores the operating system and user data but is not initialized until after the BIOS runs; storing the BIOS there would create a circular dependency preventing boot.
The BIOS (Basic Input/Output System) is a type of firmware embedded in a dedicated chip - historically a ROM and now typically a flash memory chip - that is physically mounted on the motherboard. It is the first code executed when a PC powers on, initializing hardware before handing control to the bootloader, and its physical location on the motherboard is fixed and independent of other storage devices.
An LCD monitor is a display output device and contains no programmable storage or firmware relevant to system initialization.
