First option is correct.

Step-by-step explanation:

Since we have given that

(-2x^3y^2+4x62y^3-3xy^4)-(6x^4y-5x^2y^3 -y^5)

1) Open a bracket with the sign changed to the second expression within the brackets:

$(-2x^3y^2+4x^2y^3-3xy^4)-(6x^4y-5x^2y^3 -y^5)\\\\=-2x^3y^2+4x^2y^3-3xy^4-6x^4y+5x^2y^3 +y^5$

2) Gather the like terms together:

$(-2x^3y^2+4x^2y^3-3xy^4)-(6x^4y-5x^2y^3 -y^5)\\\\=-2x^3y^2+4x^2y^3-3xy^4-6x^4y+5x^2y^3 +y^5\\\\=-2x^3y^2+4x^2y^3+5x^2y^3-3xy^4-6x^4y+y^5\\\\=-2x^3y^2+9x^2y^3-3xy^4-6x^4y+y^5$

Hence, First option is correct.
