The output $(Y)$ of the logic circuit given below is $0$ only when:

Input waveforms $A$ and $B$ as shown in Fig-$I$ are applied to the combination of gates as shown in Fig-$II$. Which of the waveforms shown in Fig-$(i)$ to Fig-$(iv)$ correctly represents the output waveform $Y$?

In the logic circuit diagram, when all the four inputs, $A, B, C, D$ are 'one' the outputs $Y_1, Y_2, Y_3$ are respectively $(1, 1, 0)$. When the inputs $A$ and $C$ are changed to zero and $B$ and $D$ are still 'one',then the outputs $Y_1, Y_2, Y_3$ are respectively change to

Which one of the following will be the output of the given circuit?

The Boolean expression $Y = A \bar{B} C + \bar{A} \bar{C}$ can be realized with which of the following gate configurations?
$A.$ One $3$-input $\text{AND}$ gate,$2$ $\text{NOT}$ gates,one $2$-input $\text{AND}$ gate,and one $2$-input $\text{OR}$ gate.
$B.$ One $3$-input $\text{AND}$ gate,$2$ $\text{NOT}$ gates,one $2$-input $\text{NAND}$ gate,and one $2$-input $\text{OR}$ gate.
$C.$ One $3$-input $\text{OR}$ gate,$3$ $\text{NOT}$ gates,and one $2$-input $\text{AND}$ gate.
