Answer
Correct option: A.
a
Here $y=(\overline{\bar{A}+\bar{B}})=\bar{\bar{\underset{\scriptscriptstyle\centerdot}{A}}}\cdot \bar{\bar{B}}=A\cdot B$
Here $y=(\overline{\bar{A}+\bar{B}})=\bar{\bar{\underset{\scriptscriptstyle\centerdot}{A}}}\cdot \bar{\bar{B}}=A\cdot B$
Thus it is an $AND$ gate for which truth table is
$\begin{array}{|c|c|c|}\hline A & {B} & {y} \\ \hline 0 & {0} & {0} \\ \hline 0 & {1} & {0} \\ \hline 1 & {0} & {0} \\ \hline 1 & {1} & {1} \\ \hline\end{array}$
