PCB Meaning in Operating Systems

The correct expansion for 'PCB' in the context of operating systems is Process Control Block.
This block contains vital details such as the process ID, process state (running, waiting, etc.), CPU registers, memory management information, and accounting information.
Therefore, Option B is the correct answer.
