Which Boolean identity correctly represents the absorption law?

MCQ 2022 Boolean Algebra Basics

Choose an Option

Answer

A + AB = A

Theory

Boolean algebra is a mathematical system used to represent and analyze logic circuits using binary variables (0 and 1). Key laws include identity, complement, distributive, and absorption laws.

Solution

Absorption law: A + AB = A(1 + B) = A · 1 = A. Hence option (A) is correct.
