The subject is "alignment", which is singular. Hence singular verb "has given" is required - eliminate C and D.
The verb "been outnumbering" is not complete - eliminate E.
The past tense "outnumbered" is incorrect - "has given rise" is in present perfect, hence the verb" outnumber" must be in present tense - eliminate B.

Correct A - added OA.

There seems to be a typo; it should be --- outnumber those in---- rather than - outnumber those is -. Outnumber those is doesn't make any logic.

how can alignment be the noun here? both alignment and isolation are noun connected with 'and'. Does they together not become plural?

It is talking about the alignment of two factors which resulted in a great diversity of species viz- 1. a fertile ecosystem 2. the fact that this ecosystem was isolated...epoch; hence alignment would be the subject and will take the singular verb.

Meaning analysis:
In Amazon, The alignment of
- a fertile ecosystem and
- isolation from other ecologies
during early geological epochs
has given rise to diversity of species,
(These species) which, in many geneses, outnumber those in other regions.

Error analysis:
There are two S-V pair and both agree with each other.
No idioms
Modifier Which clause is correctly modifying species.
Tense : No tense error because the intention of A is to say that these still outnumber and Everything is stated in present tense.

No Error.
So answer is A.

POE:

A) Correct
B) The use of HAS means we need the present tense "outnumber"
C) HAVE is incorrect
D) OF BOTH is incorrect
E) been outnumbering is incorrect, not sure what grammar rule E is violating, but "been outnumbering" sounds very wrong.
