We use "between" when we have 2 entities
We use "among" when we have more than 2 entities

Only D is left

I think this question was posted specifically to outline one of the exceptions to the rule you mentioned. 
Checking blog.oxforddictionaries and quoting - 
A good rule of thumb is that we use between when talking about a relationship of a person or thing with regard to other people or things separately and distinctly, whereas among expresses a relation collectively and more generally.
Opt for between if you’re referring to any number of specific (i.e. named) people, groups, or things:
Correct - A treaty was drawn up between France, Germany, Italy, and Greece.
Wrong - A treaty was drawn up among France, Germany, Italy, and Greece.

Official Explanation

D. The original version contains several errors that must be corrected: the proposition in for from, the adjective effective for effecting, and the preposition among for between.

CrackverbalGMAT · Answer

This question is based on Diction.

The words ‘effecting’ and ‘affecting’ in Options A and C change the meaning of the sentence.  ‘Effecting’ means ‘bringing about’ or ‘causing’. ‘Affecting’ means touching’.  Neither word can be used to describe “Arms talks” in this sentence. So, Options A and C can be ruled out.

The preposition ‘between’ is used when there are two things under discussion.  Since there are more than two countries under discussion, Options B and E can be ruled out.

Option D contains the appropriate prepositions ‘in’ and ‘among’ and the appropriate adjective ‘effective’.  This option is also the most concise.  Therefore, D is the most appropriate option .
