Solution

The correct option is D Control unit and ALU

Control unit and ALU are the two main components of the CPU.

The two typical components of a CPU include the following: The arithmetic logic unit (ALU), which performs arithmetic and logical operations. The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

The Central Processing Unit (CPU) is also known as the microprocessor or processor. The processor contains three sections called the Arithmetic Logic Unit (ALU), the Control Unit and Registers. Control unit: The Control Unit makes decisions and sends the appropriate signal down its lines to other parts of the computer.

ALU and CU is that arithmetic logic unit, another component of the processor, performs arithmetic, comparison, and other operations. While control unit is the component of the processor that directs and coordinates most of the operations in the computer.
