There is speculation that increasing cold weather was what may have been responsible for the Anasazi move from Mesa Verde to sites in other canyons.

First decision point is increasing/increasingly.
"Increase" modifies the adjective "cold" (it was getting colder) so we will use the adverb form here - increasingly. Eliminate (A) and (B).
In (C), you do not need the pronoun 'what'. Also, the use of 'had been' (past perfect) is incorrect. We don't have two events in the past. We just want to say that "A was responsible for B in the past".
In (D) too, the use of pronoun 'what' is circuitous.
(E) is direct and clean.
Hi Karishma, In fact we do have 2 events in the past. Notice that a lot of times the use of past perfect is justfied even if the sentence doesn't clearly indicates a time frame, as long as the logic clealy tell us that one event happened in the past of another event. In option C, the Anasazi move is the event in the past that happened after the weather change, I don't think this is open to debate.
The divorce of Tim's parents had been responsible for his move from Boston to LA. --- I think this is perfectly logical.
I agree with you that the use of "what" is somehow wordy, but wordy is usually not a decisive factor.
In Option E, the use of "may" is redundant right? speculation .... may, they do the same thing.
