Option A is the correct answer for the above question.

Explanation:

ALU is used to operate on the computer system. It works on a instruction of CU (Control unit). CU gives the control to ALU that which operation is performed and how it is performed. ALU is of two type - first is AU and the other is LU. AU is used to perform Arithmetic operation while LU is used to perform Logical operation. The ALU performs logical operation by comparison the operands because logical operations gives the result either true or false which comes after comparison only.

The above question asked about the work of ALU then the option A is correct answer because it states about work of ALU while the other is not because--

Option B states that The ALU compares two addition but it compares any condition. Option C states that The ALU compares two multiplications but it compares any condition. Option D states that The ALU compares two divisions but it compares any condition. Option E states that The ALU compares two subtractions but it compares any condition.
