(B) The given circuit consists of two $NOT$ gates followed by a $NAND$ gate.The inputs to the $NAND$ gate are $\bar{A}$ and $\bar{B}$.The output $Y$ of the $NAND$ gate is given by the Boolean expression:$Y = \overline{\bar{A} \cdot \bar{B}}$Using De Morgan's theorem,$\overline{X \cdot Y} = \bar{X} + \bar{Y}$.Therefore,$Y = \overline{\bar{A}} + \overline{\bar{B}} = A + B$.This represents an $OR$ gate operation.By analyzing the input waveforms for $A$ and $B$ at different time intervals,we can determine the output $Y = A + B$:- For $t - For $5 - For $7 - For $10 - For $15 - For $17 - For $t > 19$,$A=0, B=1 \implies Y=1$.Comparing this with the given options,the waveform corresponding to the $OR$ operation is represented by option $B$.

Identify the correct output signal $Y$ in the given combination of gates (as shown) for the given inputs $A$ and $B$.
