Explanation
Answer: C - The control processing unit (CPU) has several different types of registers, each containing information about the instruction set and data that must be executed to include general register, special register, and program counter register. The general registers are used to hold variables and temporary results as the ALU works through its execution steps. The special registers are dedicated registers that hold information such as the program counter, stack pointer, and program status word. The program counter register contains the memory address of the next instruction to be fetched. After that instruction is executed, the program counter is updated with the memory address of the next instruction set to be processed.
