B it is
a pronoun "they" is needed to link the independent clause to the dependent one and make pronoun refer to "cells"

Vote for (B)...

only (B) and (D) uses contrasting words.
In (D) beating is modifying the Noun Clause while we need a reference to m.. c.. s.. So this is out.

In (B), "they" perfectly refers to "mammalian circulatory system"

B will make run on senetnce..

Answer should be D. This choice indicates the necessary contract reequired to convey the intended meaning.

The cells beat in UNISON but still ADOPT specialized orientation exclusive of one another.

"they" is needless here and "yet" is stronger than "while" in expressing the contradiction.

I misinterpreted this question but I don't like this question in the sense that it should have had a comma after "heart" to give the sentence a break and make it clear that "the cells" are part of "the area of the heart" and "the cell" starts an independent clause of its own.

Written as such, it sounds like "in the area of the heart [where] the cells adhere to one another..."
In this case, the above portion would become a dependent clause which would be linked by pronoun "they" to introduce the last part of the sentence which would be an independent clause.
To me, this question should have included that comma.

This is the type of a sentence, where we have to look at the meaning a little more closely. The underlined portion is a contrast.

A. - wrong, shows no contrast, 'doing this and doing that', while it should be 'doing one thing, yet doing another thing [which is contrasted with the first]'

B - run on sentence, we need a semi-colon after 'adhere to one another' in order to make this work, because B offers us a complete sentence with subject and verb

C - clearly wrong, changes the meaning of the sentence: it puts adhere, beat and adopt on the same level, whereas, beat and adopt simply explain what is meant by adhere

E - too wordy, plus jult like in B, it is a run-on sentence. It gives an effort an making a contrast, but fails and changes the meaning of the sentence once again.

I hope that aids your understanding, Syamee.[/b]
