Which logic gate is represented by the following truth table?

$A$	$B$	$Y$
$1$	$1$	$0$
$1$	$0$	$0$
$0$	$1$	$0$
$0$	$0$	$1$

The output of a $NOR$ gate is $HIGH$ when

$A$ $NOR$ gate and a $NAND$ gate are connected as shown in the figure. Two different sets of inputs are given to this setup. In the first case, the inputs to the gates are $A=0, B=0, C=0$. In the second case, the inputs are $A=1, B=0, C=1$. The output $D$ in the first case and second case respectively are

What will be the input of $A$ and $B$ for the Boolean expression $(\overline{A + B}) \cdot (\overline{A \cdot B}) = 1$?

The logic gate combination circuit shown in the figure performs the logic function of

In the given circuit,the output $Y$ becomes zero for the inputs
