(D) $NAND$ gate produces a low output $(0)$ only when both inputs are high $(1)$. Otherwise, it produces a high output $(1)$. The truth table for a $NAND$ gate is:| $A$ | $B$ | $Y = \overline{A \cdot B}$ ||---|---|---|| $0$ | $0$ | $1$ || $0$ | $1$ | $1$ || $1$ | $0$ | $1$ || $1$ | $1$ | $0$ |By analyzing the input waveforms for $A$ and $B$ at different time intervals:$1$. For the first interval, $A=1, B=1$, so $Y=0$.$2$. For the second interval, $A=0, B=0$, so $Y=1$.$3$. For the third interval, $A=0, B=1$, so $Y=1$.$4$. For the fourth interval, $A=1, B=0$, so $Y=1$.$5$. For the fifth interval, $A=1, B=1$, so $Y=0$.$6$. For the sixth interval, $A=0, B=0$, so $Y=1$.$7$. For the seventh interval, $A=0, B=1$, so $Y=1$.Comparing this sequence $(0, 1, 1, 1, 0, 1, 1)$ with the given options, the waveform in image $D$ matches this output.

The output from a $NAND$ gate having inputs $A$ and $B$ given below will be:
