Which of these is NOT normally stored in a process control block (PCB)?
Correct answer C. The source code of the program
Explanation
The PCB is the kernel's record of a process: its state, program counter, saved registers, scheduling information, memory-management data, accounting details and list of open files. The executable code lives in the process's memory image, and source code is not kept anywhere by the kernel. Everything else listed is exactly what a context switch saves and restores.
