(D) The given circuit consists of two $NAND$ gates acting as $NOT$ gates (since their inputs are shorted) followed by a $NOR$ gate.Let the inputs be $A$ and $B$.The output of the first $NAND$ gate (acting as $NOT$) is $\bar{A}$.The output of the second $NAND$ gate (acting as $NOT$) is $\bar{B}$.These two outputs are fed into a $NOR$ gate.The output $Y$ of the $NOR$ gate is given by $Y = \overline{\bar{A} + \bar{B}}$.Using De Morgan's theorem,$\overline{\bar{A} + \bar{B}} = \overline{\bar{A}} \cdot \overline{\bar{B}} = A \cdot B$.Thus,the circuit performs the $AND$ operation.
