Sentence Correction

A peculiar feature of the embryonic mammalian circulatory system is that in the area of the heart the cells adhere to one another, beating in unison and adopting specialized orientations exclusive of one another.

(A) beating in unison and adopting
(B) they beat in unison while adopting
(C) beat in unison, and adopt
(D) beating in unison yet adopting
(E) even though they beat in unison and adopt

OA after few reasonable explanations.

Since the author is talking about PECULIAR feature, this feature is mentioned only in D. Beating in Unison YET adopting...
So I would go with D.
(A too is correct sentence grammatically but doesnt justify the use of peculiar earlier in the sentence).
