The idea of "that" baffles me because
1) I understand that GMAT uses "that" to modify the preceding noun "substances". However, the meaning does not make sense to me because it is not all the substances that "tell(s)" the gene when to become active or not, but that "one" substance. That is the meaning of the sentence to me. If we are applying GMAT's rule strictly though, I guess we have no problems.

Basically the sentence is trying to say:

- There are many substances that tell individual genes both when to become active and when to remain quiescent.
- Biologists have found one of them.

Quote:
2) But, as in this link http://gmatclub.com/forum/horses-have-a-unique-system-of-interlocking-ligaments-and-bones-192969.html, i can say sufficiently that the "that" can modify the "XX of YY and ZZ" if it sufficiently makes sense for the meaning of the statement.

This horses example is one of the numerous examples in OG that illustrate that that can modify a faraway word; but it all depends on the logic. For example in the horses example, clearly the unique system serves as a kind of sling.

Quote:
3) This means that there should not be any hard rule or there are exceptions to this rule, especially if it makes sense. So if, say the exceptions, liken that of "XX of YY, which" when "which" modifies XX, doesn't it also mean that our question here, with "that", should modify "one" and give our answer "tells"?

The only exception to this one of pattern is when the word only appears as part of this structure. For example:

Mercedes is the only one among the luxury cars that has a global fan following.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses that, its application and examples in significant detail. If someone is interested, PM me your email-id, I can mail the corresponding section.

Thanks both, much appreciated.

I guess what i failed to understand is the meaning of the sentence that will point me to the correct verb.

That refers to substances and that acts here as noun modifier so we know that " that " here is plural so we have to use plural verb
So C,D and E are out
B is rather written awkwardly and it is wordy .
