Answer:

First option:
-10d^4+17d^2s-6s^2

Explanation:


\left(-2d^2+s\right)\left(5d^2-6s\right)

Use FOIL method to expand:
\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd


\left(-2d^2\right)* 5d^2+\left(-2d^2\right)\left(-6s\right)+s* 5d^2+s\left(-6s\right)


-2*5d^2d^2+2* 6d^2s+5d^2s-6s^2


-10d^4+12d^2s+5d^2s-6s^2


-10d^4+17d^2s-6s^2
