both
D
none
Explanation: 

Detailed explanation-1: -What is an arithmetic-logic unit (ALU)? An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).

Detailed explanation-2: -The correct answer is Arithmetic Logic Unit. Arithmetic Logic Unit (ALU): It performs all Arithmetic Operations and Decision-Making operations.

Detailed explanation-3: -The function of an ALU is to take binary inputs, execute the operation, and create, store, and distribute binary output. ALUs make arithmetic and logical calculations within a computer’s CPU.

Detailed explanation-4: -An arithmetic logic unit (ALU) is a key component of a computer’s central processor unit. The ALU performs all arithmetic and logic operations that must be performed on instruction words. The ALU is split into two parts in some microprocessor architectures: the AU and the LU.
