(C) The given circuit consists of two $NOT$ gates followed by a $NOR$ gate.Let the inputs be $A$ and $B$.The outputs of the two $NOT$ gates are $\overline{A}$ and $\overline{B}$.These are the inputs to the $NOR$ gate.The output $Y$ of the $NOR$ gate is given by:$Y = \overline{\overline{A} + \overline{B}}$Using De Morgan's theorem,$\overline{X + Y} = \overline{X} \cdot \overline{Y}$.Therefore,$Y = \overline{\overline{A}} \cdot \overline{\overline{B}}$Since $\overline{\overline{A}} = A$ and $\overline{\overline{B}} = B$,we get:$Y = A \cdot B$This is the Boolean expression for an $AND$ gate.

The logic gate combination shown in the figure represents which of the following gates?
