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

IMO (D)

Hi,

Here as we see the structure of the sentence, we look at a peculiar feauture
i.e cells adhere-- beating in unison and adopting. This is wrong because adopting special orientations requires a contrast here.

The cells beat in unison yet adopting.. right.

So we can see A,C,E are having "and". Can be eliminated. B is a running sentence-- so eliminated

The Correct answer is D.
