(A) $NAND$ gate is defined as the logical combination of an $AND$ gate followed by a $NOT$ gate. Mathematically,if the inputs are $A$ and $B$,the output of the $AND$ gate is $Y' = A \cdot B$. Passing this through a $NOT$ gate results in the final output $Y = \overline{A \cdot B}$. Therefore,the correct representation is an $AND$ gate followed by a $NOT$ gate.

Which of the following represents a $NAND$ gate?
