The Correct Option is B

Solution and Explanation

Output \(Y\) is 0 only when both \(A = 0\) and \(B = 0\); for every other input combination \(Y = 1\).
This is the OR function \(Y = A + B\).
AND would give 1 only for (1,1); NAND would give 0 only for (1,1); NOR would give 1 only for (0,0). None of these match.
Answer: (2) OR - Gate
