basic structure: Gould has argued that traits are not X but are Y

so you need the second "are"

"because" is preferred over "due", so C D E are left
E is out: "enhancing reproduction" is not right

between C and D, only D repeats the needed "are" in the parallel structure

I don't agree with you..
the correct structure should be:

are not X, But Y

NOT X, BUT Y is the correct idiom as GMAT asks a lot of question based on this.

Even I went with C. I am also not convinced with the solution given on the thread!
