(B) $NAND$ gate produces an output of $0$ only when both inputs are $1$. Otherwise,it produces an output of $1$.Based on the input waveforms for $A$ and $B$:- For $t = 0$ to $2 \ s$: $A=0, B=0 \implies Y=1$.- For $t = 2$ to $4 \ s$: $A=1, B=0 \implies Y=1$.- For $t = 4$ to $6 \ s$: $A=0, B=0 \implies Y=1$.- For $t = 6$ to $8 \ s$: $A=1, B=1 \implies Y=0$.- For $t > 8 \ s$: $A=0, B=0 \implies Y=1$.Comparing this sequence $(1, 1, 1, 0, 1)$ with the given options,the waveform in option $B$ matches this output.

The real-time variation of input signals $A$ and $B$ are as shown below. If the inputs are fed into a $NAND$ gate,then select the output signal from the following.
