Which polynomial correctly combines the like terms and expresses the given polynomial in standard form?

9xy3 - 4y4 - 10x2y2 + x3y + 3x4 + 2x2y2 - 9y4

-13y4 + 3x4 - 8x2y2 + x3y + 9xy3

-13y4 + x3y - 8x2y2 + 9xy3 + 3x4

3x4 - 8x2y2 + x3y + 9xy3 - 13y4

3x4 + x3y - 8x2y2 + 9xy3 - 13y4

    9xy^3 - 4y^4 - 10x^2 * y^2 + x^3 * y + 3x^4 + 2x^2 * y^2 - 9y^4

    Arranging the different terms of the polynomial:

    3x^4 + x^3 * y - 10x^2 * y^2 + 2x^2 * y^2 + 9xy^3 - 4y^4 - 9y^4

    3x^4 + x^3 * y - 8x^2 * y^2 + 9xy^3 - 13y^4

    Therefore, the third choice is the correct answer.
