Solution

The correct option is B Control unit and ALU

The two main components of the CPU is Control unit and ALU.

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.

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).

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.
