Question

Choose the correct logic circuit for the truth table shown in the original figure, where the output Y is 0 for inputs 00 and 01, and 1 for inputs 10 and 11.

From the truth table: A B → Y 0 0 → 0 0 1 → 0 1 0 → 1 1 1 → 1. The output depends only on A and is independent of B. Therefore the required Boolean relation is Y = A. Evaluating the four circuits shown in the original figure, only circuit 4 reduces to Y=A for all four input combinations. Correct option: D.
