(B) To construct an $AND$ gate using $NAND$ gates,we first pass the inputs $A$ and $B$ through a $NAND$ gate. The output of this first gate is $Y_1 = \overline{A \cdot B}$.Next,we pass this output $Y_1$ through a second $NAND$ gate whose inputs are shorted together. $A$ $NAND$ gate with shorted inputs acts as a $NOT$ gate. Therefore,the final output is $Y = \overline{Y_1} = \overline{(\overline{A \cdot B})} = A \cdot B$.Thus,$2$ $NAND$ gates are required to construct an $AND$ gate.
