As Charles Darwin observed, natural selection operates whenever individuals of one genetic composition are better at reproducing than that of others.
A. that of others
B. the other
C. another
D. those of another
E. that of the next

Clearly we need those to refer to plural noun individuals, so only D is correct.

A & E use "that" are not correct.

B & C are incorrect since the sentence makes comparison of genetic composition in each individual

Actually, the same question has been posted here

The comparison must be made between "individuals of one genetic composition" and "individuals of another genetic composition."

Therefore, (A) and (E) are wrong because "that" is singular; we're supposed to be comparing individual's' (plural).
(B) and (C) are wrong because "other"/"another" refers to another genetic composition; therefore, these are faulty comparisons, because there's no word to suggest "individuals" (we MUST compare individuals to other individuals, not to a composition) and that leaves us with answer choice (D).

As for the distinctions:-

"the other" is used when there are only two things.
I chose one of the two dinner options; my date chose the other.

"another" is used for another of an indefinite number of things.
Usually, i'll order one entre and my date will order another, so that we can each try some of both.

"each other" refers to interaction between exactly two things or people.
My date and i usually sit next to each other, rather than across from each other.

"one another" also refers to interaction, but there may be more than two things/people.
The holiday season offers many occasions for people who have not seen one another in many months to reunite.
