Logic Gates

To get output 1 for the following circuit, the correct choice for the input is

Show answer and solution

Answer: (b)

OR then AND: $Y = (A + B) \cdot C$ .
Y = 1 needs $C = 1$ and at least one of A, B equal to 1.
Only (b) has $C = 1$ : $Y = (1 + 0) \cdot 1 = 1$ .
So the answer is (b) $A = 1, B = 0, C = 1$ .
