(C) The circuit consists of an $OR$ gate followed by an $AND$ gate.Let the output of the $OR$ gate be $Y_1$. Then $Y_1 = A + B$.The final output $Y$ is the output of the $AND$ gate,which takes $Y_1$ and $C$ as inputs.Therefore,the final output is $Y = Y_1 \cdot C = (A + B) \cdot C$.We want the final output $Y = 1$.For an $AND$ gate to give an output of $1$,both its inputs must be $1$.Thus,we need $Y_1 = 1$ and $C = 1$.Since $Y_1 = A + B$,for $Y_1$ to be $1$,at least one of $A$ or $B$ must be $1$.Checking the options:For option $C$: $A = 1, B = 0, C = 1$.$Y_1 = A + B = 1 + 0 = 1$.$Y = Y_1 \cdot C = 1 \cdot 1 = 1$.Thus,the correct input is $A = 1, B = 0, C = 1$.

Input $A$	Input $B$	Output $Y$
$0$	$0$	$1$
$0$	$1$	$1$
$1$	$0$	$1$
$1$	$1$	$0$

To get an output $1$ from the circuit shown in the figure,the input must be
