(B) The circuit consists of a $NOR$ gate followed by an $AND$ gate and an $OR$ gate. Let the output of the $NOR$ gate be $C = \overline{A + B}$. Given $A = 1$ and $B = 1$, the output of the $NOR$ gate is $C = \overline{1 + 1} = \overline{1} = 0$. The output $y_1$ is the output of an $AND$ gate with inputs $A$ and $C$. Thus, $y_1 = A \cdot C = 1 \cdot 0 = 0$. The output $y_2$ is the output of an $OR$ gate with inputs $B$ and $C$. Thus, $y_2 = B + C = 1 + 0 = 1$. Therefore, the values are $y_1 = 0$ and $y_2 = 1$.

Three logic gates are connected as shown in the figure. If the inputs are $A = 1$ and $B = 1$, then the values of $y_1$ and $y_2$ respectively are
