(A) numbers of ospreys, whose huge nests--- Correct
(B) numbers of ospreys, their huge nests-- 2 IC clauses connected by a comma; Wrong
(C) amounts of ospreys, the huge nests of which-- Ospreys can be counted, so use of amounts is wrong
(D) nests of ospreys they---meaning changes
(E) numbers of ospreys, and their huge nests-- makes a DC clause to IC clause, impacting the meaning

IMO A

(A) numbers of ospreys, whose huge nests( correct, whose correctly modifies ospreys,conveys the correct meaning)
(B) numbers of ospreys, their huge nests( change in meaning)
(C) amounts of ospreys, the huge nests of which( amounts is incorrect)
(D) nests of ospreys they( use of they immediately after ospreys is incorrect grammatically)
(E) numbers of ospreys, and their huge nests( change in meaning)

Is it correct to use their as a subject in Gmat context?their is an adjective as well as possessive form of they.
In this sentence their refers to ospreys?

Will go with choice A because of meaning.

Thanks

The Coast Guard recently redesigned channel markers in the Chesapeake Bay to accommodate large numbers of ospreys, whose huge nests formerly obstructed the lights.

(A) numbers of ospreys, whose huge nests
(B) numbers of ospreys, their huge nests
(C) amounts of ospreys, the huge nests of which
(D) nests of ospreys they
(E) numbers of ospreys, and their huge nests


First of all, usage of "numbers of" is not incorrect when used by itself. However when used with "A numbers of" or "THE numbers of", it is incorrect.
In option B, "their huge nests" is an independent clause and therefore must be preceded by a conjunction. This is a run on sentence and hence incorrect.
In option C, use of amounts is incorrect. Amount is used for uncountable nouns and since ospreys can be counted, it's wrong. Also "the huge nests of which.." is wordy. This is also wrong.
In option D, "nests of ospreys they" is awkward and unidiomatic.
In option E, introduction of an independent clause starting with "and" is unnecessary and fails to convey the meaning properly.
Option A is grammatically correct."Whose" correctly refers to "ospreys". This should be the answer.

(A) numbers of ospreys, whose huge nests
(B) numbers of ospreys, their huge nests
(C) amounts of ospreys, the huge nests of which
(D) nests of ospreys they
(E) numbers of ospreys, and their huge nests


(A) whose huge nests correctly modifies ospreys. Keep it.
(B) 'Their huge nests' has ambiguous antecedent. It could be Coast Guard or ospreys. Eliminated.
(C) The modifier 'which' is far away from what it modifying. Also, which is used not non living things. Eliminated.
(D) Clearly incorrect.
(E) Here, Emphasis is on 'and' which distorts the meaning of the sentence.

IMO, Option A.

(A) numbers of ospreys, whose huge nests
(B) numbers of ospreys, their huge nests
(C) amounts of ospreys, the huge nests of which
(D) nests of ospreys they
(E) numbers of ospreys, and their huge nests

ospreys appear to be countable; therefore, amount is incorrect. Eliminate (C)
(E) fails at parallelism both side of "and" does not have a similar structure
(D) they is not clear which plural noun it refers to

(A) and (B)
(B) has two independent clauses without proper conjunction or semicolon

Ans: (A)

(A) numbers of ospreys, whose huge nests --> the best answer choice. "whose" is a good choice since nests are ospreys'.
(B) numbers of ospreys, their huge nests --> run-on sentence
(C) amounts of ospreys, the huge nests of which --> ospreys are countable. Therefore, "amounts" is not right.
(D) nests of ospreys they --> what obstructed the lights was large numbers of ospreys and their nests, not large nests.
(E) numbers of ospreys, and their huge nests --> The Coast Guard redesigned...and their huge nests obstructed... --> this sounds like "because of the redesign, their huge nests obstructed.." Actually, the meaning is exactly opposite.

Official Explanation :

Choice B and D are run on sentences.

In choice C, the use of “amount” is incorrect since “ospreys” is a countable noun.

Choice E distorts the meaning.

Hence, A is the best choice.
