What do POST and processor removal involve?

a) What does POST stand for?
The correct option is A.
POST stands for Power-On Self-Test. This is a diagnostic test sequence that a computer's basic input/output system (BIOS) or unified extensible firmware interface (UEFI) runs to check if the computer's hardware is working correctly before booting the operating system.

b) How is a processor removed?
The correct option is C.
To remove a processor from its socket on a motherboard, you typically lift the socket lever. This releases the clamping mechanism that holds the processor in place, allowing it to be gently lifted out.
