Answer:

$-3x^2 * x = -3x^3\\y * y = y^2$

$(-3x^2y)(5xy^2 + xy)\\$

Use F.O.I.L, (First Outer Inner Last) to multiply. Start with -3x^y * 5xy^2

Start with similar terms

$-3x^2 * 5x = -15x^3\\y * y^2 = y^3\\Therefore,\\-15x^3y^2$

Move onto the xy portion of the problem

$-3x^2y(xy)\\$

Start with similar terms

$-3x^2 * x = -3x^3\\y * y = y^2\\Therefore,\\-3x^3y^2$

Combine the two together

$-15x^3y^3 - 3x^3y^2\\$

The answer is Option A
