The output $Y$ for the given inputs $A$ and $B$ to the circuit is :
Answer: (B) see figure
The upper AND gate receives $A$ and $B$: output $AB$.
The lower AND gate receives $\overline{A}$ (through the bubble) and $B$: output $\overline{A}B$.
The OR gate gives $Y = AB + \overline{A}B = B(A + \overline{A}) = B$.
So $Y$ simply follows input $B$: $1$ from $0$ to $2$ s, $0$ from $2$ to $3$ s, then $1$ again, which is option (B).
