The correct answer is:
$\mathrm{Y}=(\overline{\mathrm{A}} \cdot \mathrm{B})+(\mathrm{A} \cdot \overline{\mathrm{B}})$
Truth table
Output equation: $\mathrm{Y}=\mathrm{A} \oplus \mathrm{B}=(\overline{\mathrm{A}} \cdot \mathrm{B})+(\mathrm{A} \cdot \overline{\mathrm{B}})$
Key points to remember:
(1) the output is low when both the inputs are the same
(2) the output is high when both the inputs are different
