One of the following values of inputs A , B and C respectively gives output ( Y ) of the following combination of logic gates as ' 1 ' is

Step-by-step solution

The circuit's output Y represents the logical AND of input A with the OR of inputs B and C , expressed as Y = A (B + C) . For Y to be 1 , both conditions A = 1 and B + C = 1 must hold true. The OR condition B + C = 1 requires at least one of B or C to be 1 . Evaluating the options: only choice D , with A=1 , B=0 , C=1 , satisfies both A = 1 and B + C = 1 since 0 + 1 = 1 , leading to Y = 1 1 = 1 . The correct input combination is D .
