a preposition question

[curious]

The wording of the sentence and alternatives below belongs to me. I would like to know if there is anything wrong with them, both structurally and semantically. (For example, is "made against him" redundant?) I thought A correct. Thanks in advance.

As the last suspect was absolved ---- all the accusations made against him, for a time there was no one else to be held accountable ---- the crime.

A) of / for

B) for / with

C) in / for

D) from / to

E) on / of

IMO, the correct answer is a).
