Four logic gates are connected as shown in the figure. If the inputs are $A=0$,$B=1$ and $C=1$,then the values of $y_1$ and $y_2$ respectively are

The $NOR$ gate is a combination of which two gates?

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.
Choose the correct answer from the options given below.

In the given circuit,$A$ and $B$ are two inputs and $C$ is the output. Which logic gate does this circuit represent?

The output of an $OR$ gate is connected to both inputs of a $NAND$ gate. This combination is equivalent to a:

What will be the outputs $Y$ for the inputs $(A = 1, B = 0)$,$(A = 1, B = 1)$,and $(A = 0, B = 0)$ respectively?
