Well, I think you inadvertently hit the nail on the head when you said "they say that innate mechanicms also play a role".
The blank is prefaced by "So", indicating that it will be the conclusion to the argument. Do conclusions of arguments normally ask whether the premises were true?
If I said,
"John loves chocolate, but he also loves strawberry, so I guess the question that ought to be asked is does John really love chocolate?"
It just wouldn't make sense as a conclusion. The author already established (already believes) that innate mechanisms are a contributing factor, so why would his conclusion call that idea into question?
What you want to look for with most of these Logical Completion questions is an idea that safely synthesizes the multiple threads leading up to it. (B) would only be focused on one thread, while (E) intertwines both of the ideas mentioned.
When I say "SAFELY" synthesizes, I mean beware of going overboard with extreme language, as (A) "fully explained", (C) "solely", and (D) "most" all do.
Hope this helps. Let me know if you have lingering qualms.
