D is my pick
To emphasize the contrast - 'peculiar feature...beating in unison...orientations exclusive of one another', we need 'yet' here.
This logic takes precedence over the 'parallelism' and other GMAT'ically correct stuff!

The underline portion of the sentance is a subordinate clause. Therefore, we should use a participle, i.e. -ing, to the clause. Eliminate B, C and E.

"A peculiar feature...." gives the sense that we need to contrast on feature from another. Therefore, we need to use" beating in unison yet adopting." The best answer is D.

Another D.

The part of the sentence that is not underlined give it away that there should be a shift between the two. Only D does it correctly.

First, I would have chosen C. But after all your good explaination, I go with D. Tricky one.
