(A) it and apply primer before applying the paint - Correct
(B) it and prime it and paint it - Repetitive
(C) it, then prime it, then paint it - Repetitive
(D) the surface and apply primer before you apply paint to the surface - Repetitive

All of the answer choices except are wordy n repetitive. Hence (A) is correct.

(A) seems to be the best answer.

But my doubt is regarding the pronound "it"

to sand [u]it and apply primer before applying the paint[/u].

too many its are looking confusing. isn't it ?

I would choose E. I have a problem with A because I think apply primer is ambiguious without specifying what you're applying primer to.
