killer1387 could you please explain why A is wrong.

I am finding A as the correct answer. I am confused between A and C and I choose A and not C.

As this is the ongoing procedure to maintain, I chose A.

(A) in the ongoing maintenance of
(C) maintain

In A the word "ongoing" is not required the word maintenance in itself speaks in general of the intended meaning. The sentence says "ideally" ie. in general view. we can hence say when the maintenance happens those diplomat guys should help. Adding "ongoing" is at best changing the meaning.
The word "ongoing" is problematic in every respect. its redundant/ambiguous.

C is concise/ unambiguous/ not redundant in depicting the intended meaning of the sentence.
