Hi,

Can someone pls clarify usage in following sentence:

In order to evenly and effectively paint a rough surface, it is necessary to sand it and apply primer before applying the paint.

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

The OA is A.

As per what I understand it does not make sense to use 'it' in possessive form and as a personal pronoun in the same sentence.
