Logic Gates

In the combination of the following gates the output Y can be written in terms of inputs A and B as

Show answer and solution

Answer: (b)

Upper AND gets A and $\bar{B}$ : $A \cdot \bar{B}$ .
Lower AND gets $\bar{A}$ and B: $\bar{A} \cdot B$ .
OR gate: $Y = A \cdot \bar{B} + \bar{A} \cdot B$ (XOR).
So the answer is (b).
