Show answer & explanation
Correct answer: A
Key insight: the function's output depends only on X. When X = 0 the output is 0, and when X = 1 the output is 1, regardless of Y.
If X = 0: rows (0,0) and (0,1) both produce 0.
If X = 1: rows (1,0) and (1,1) both produce 1.
Therefore the Boolean function simplifies to f(X, Y) = X.
