(D) The circuit consists of an $OR$ gate $(G_1)$ followed by a $NAND$ gate $(G_2)$.Let the output of the $OR$ gate be $Y$. Then $Y = A + B$.The final output $D$ is the output of the $NAND$ gate, which is $D = \overline{Y \cdot C} = \overline{(A + B) \cdot C}$.Case $1$: $A=0, B=0, C=0$.$Y = 0 + 0 = 0$.$D = \overline{0 \cdot 0} = \overline{0} = 1$.Case $2$: $A=1, B=1, C=0$.$Y = 1 + 1 = 1$.$D = \overline{1 \cdot 0} = \overline{0} = 1$.Thus, the outputs are $1, 1$.

What is the output $D$ for the inputs $(A=0, B=0, C=0)$ and $(A=1, B=1, C=0)$ respectively?
