The correct option is B
$2 xy + 7 y$

Justification of answer:
To simplify: $\frac{(2 x + 7) \times 5 y}{5}$
$\frac{(2 x + 7) \times 5 y}{5}$ $= \frac{(2 x + 7) \times 5 \times y}{5}$
$= \frac{(2 x + 7) \times 1 \times y}{1}$
$= (2 x + 7) \times y$
$= 2 xy + 7 y$
Thus,option B is the correct answer
