B is wrong as in usage of "while"
C - "act as" same as above and it wrongly used
D is wrong - since "even though" follows "Allthough", which is wrong usage
E - "Although" and "but"

A is the correct answer. What is the OA?

Can somebody explain why usage of 'while' is incorrect.

The middle part is in between 2 parts of a sentence. Hence, "Although" and "while" don't go together. Just remove the middle part between the commas and try reading the sentence. You will get my point.

Is it A?

To have contrast with although we need present tense with they after the ','. Only A fulfills that requirement.

I think its E because first part of the sentence is benefiting Earth and second part is hurting Earth. Therefore, but is required to show contrast.

It has to be A. None of the others are complete thoughts.

Second thought, although and but don't go together, should be A. What's OA?

Try to understand the meaning of the sentence and author's intention first.

Both "although" and "while" introduces dependent clause - you can't have sentence comprising subordinate clauses only.

I think its E because,

A , B and C its unclear who does what...
D 'it' is not required.
E remains

Only A seems to be grammatically correct.
