Question

Select correct truth table. 

• A.
• B.
• C.
• D.

Hint:

Always simplify the Boolean expression first, then prepare the truth table for accuracy.

Answer 1

The Correct Option is D

Step 1: Writing Boolean expression from logic circuit. 
From the given logic circuit, the output is: 
\[ Y = (\overline{A} \cdot B)\cdot \overline{A} = (\overline{A} + \overline{B})A = A\overline{B} \] 

Step 3: Matching with given options. 
The above truth table matches option (4).
