Question

In Boolean algebra \( A + A' = \)

• A. A
• B. A'
• C. 1
• D. 0

Hint:

In Boolean algebra, \( A + A' \) always simplifies to 1 due to the complement law.

Answer 1

The Correct Option is C

Step 1: Apply the law of complement in Boolean algebra, which states that \( A + A' = 1 \).


Step 2: Therefore, the result of \( A + A' \) is always 1.
