+1 A

"both...and...." requires paralelism. The first word in each of both elements must be of the same type (noun, preposition, etc.).

One of the XYZs means that the sentence has plural subjects. Hence eliminate C, D and E. B is very wordy and not parallel.

Hence A remains.

A wins over B because it is concise.

Biologists believe that they have found one of the substances that tell individual genes both when to become active and when to remain quiescent in the earliest phases of an embryo’s development.

(A) tell individual genes both when to become active and when to remain
(B) tell individual genes both at which time they should become active or should remain
(C) tells individual genes both when to become active or remain
(D) tells individual genes both when to become active or when to remain
(E) will tell an individual gene both about when it should become active and remain

Kindly explain the reasoning against each option!

The rule that i picked up from a discussion for a similar question:

one of +noun(prural)+that/who takes prural verb
one of + noun(prural) without a relative ronoun takes singular

Hence, C and D are out, and A is parallel, Hence A....

In this question,

"Tell" (plural form) does not modify 'substances', rather it modifies 'one of the substances' (singular).

The point to be noted here is that how can the plural verb 'Tell' modify singular subject 'One of the substances'.

As the sentence has 'BELIEVE' in it, the verb can only take the base form. So irrespective of the subject being singular/plural, the verb will always take the base form.

Hence the correct answer is 'A'.

From the posts, it is not very clear to me, when we can consider "that" referring to a relative plural noun or a phrase. In this case I understand that, "that" is actually referring to substances and hence verb "tell" should be in plural form.

Can you please elaborate this with example which identify use of "that" as relative pronoun modifier and phrase modifier.

In fact there are four uses of "that":

1. I know that you have studied hard.... "that" introduces a clause. For understanding, consider "that" a conjunction, though technically it is not - it is the object of the verb "know".

2. I hate dogs that bark. .... "that" is used as a relative pronoun (can be singular or plural - here "that" is plural because it replaces "dogs").

3. The house beside the river is more beautiful than that on the top of the hill..... "that" creates a new copy of the noun "house" (can only be singular - for plural nouns, use "those")

4. I like that book..... "that is used as a demonstrative adjective (can only be singular - for plural nouns, use "those")
