My choice A. All other choices distort the meaning of the sentence.

What is known?, the number? or humans?
In this case, the number is known. In the sense, ABC are out.
Between D and E, I go for E.

^ E ^

"humans" in a passive form in A, B and C are not correct to modify the plant and animal species. D sounds awkward too.

Would go for A. E is no good because of passive construction.

Even though it is a little awkward, I think A is right too. E changes the meaning slightly and is passive.

I would go with A.
E has more degree of passiveness.

"The number of .." should be singular. "E" violates the rule.

A.

The only other close option is E, and it is passive. Hence A.

The GMAT almost always prefers the active voice.

(A) edges over E.

The number of ... is over 800 - main clause
the underlined part following the relative pronoun that has no flaws

Rearranging the words for better understanding
(that) humans are known to --> (that) are known to humans which in turn act as a subject of the relative clause

the remaining sentences cite the reason for the extinction of species is ONLY humans
