In this question i looked at option B and i was a little uncertain about the parallelism of the two elements because the idiom both X and Y is a closed parallel construction and both the elements are supposed to start with a similar constructio.. X starts with a possessive followed by a noun and Y starts with Noun modifier followed by a noun. can someone explain this a little.

Hello Jayantalawadhi,

We hope this finds you well.

To answer your query, "Einstein's theory of relativity" and "the better ability to observe extremely distant astronomical objects" are sufficiently parallel, as they are both noun phrases; two elements need not be identical in structure to be parallel.

We hope this helps.
All the best!

can have because of in the answer choice since it should be followed by a reason/clause

whereas we have nouns as reasons
theory and ability
A, D and E are wrong due to this.

b/w B and C B is more idiomatically structured.

That cannot be the reason since because of is followed by noun phrases and because is followed by a clause. So in this case because of can refer to the noun phrases.
