This sentence has four errors. First, the subordinate clause “whose funeral was
sparsely attended being buried in an unmarked communal grave” is awkward
grammatically and ambiguous in meaning; the clause could be interpreted to mean
that the funeral was sparsely attended at the time Mozart was being buried, or it could
be interpreted to mean that the funeral was sparsely attended because Mozart was
buried in an unmarked grave. Second, it is not clear whether the possessive
“Beethoven’s” refers to “funeral” or to “grave.” Third, the sentence makes an illogical
comparison between Mozart and either Beethoven’s funeral or Beethoven's grave.
Finally, the prepositional phrase “near the graves of Schubert and Brahms” is a
misplaced modifier. Since it immediately follows “cemetery,” it appears to describe the
location of the cemetery rather than that of the grave.
(A) This choice is incorrect since it repeats the original sentence.
(B) First, the subordinate clause “whose funeral was sparsely attended being buried
in an unmarked communal grave” is grammatically awkward and ambiguous in
meaning. Second, while the introduction of “funeral” makes the possessive
“Beethoven’s” unambiguous, the sentence still illogically compares “Mozart” to
“Beethoven’s funeral.” Finally, the past tense is used illogically in the clause “his final
resting place was ….” Since this clause discusses Beethoven’s final resting place, it
describes a state of being that is still true today; hence, the use of the present tense
is appropriate to describe where Beethoven’s body currently lies.
(C) “Mozart” is followed by two clauses, “whose funeral was sparsely attended” and
“he was buried in an unmarked communal grave.” The second of these clauses is
incorrect because: 1) it should be a subordinate clause modifying Mozart, and should
therefore start with "who was buried", and 2) it should be parallel to the first clause,
and should therefore start with "who was buried", and 3) it should not make the
illogical assertion that “Unlike Mozart, he [Mozart] was buried….”.
(D) This choice makes an illogical comparison between "Mozart" and "Beethoven’s
funeral." In addition, the prepositional phrase “near the graves of Schubert and
Brahms” is a misplaced modifier. Since it immediately follows “cemetery,” it appears
to describe the location of the cemetery rather than that of the grave.
(E) CORRECT. “Mozart” is now modified by two subordinate clauses, “whose funeral
was attended….” and “who was buried ….,” each properly introduced by the relative
pronouns “whose” and “who” respectively. In addition, “Mozart” is now logically
compared to “Beethoven.” Finally, the phrase “near the graves of …” unambiguously
modifies “lies buried.”

+1 for E for correct comparison of Mozart and Beethoven.

E is correct for reasons stated above.

Explanation:

I will try to address this question in an elegant way. Lets see
Their is a preposition HIS IN "HIS FINAL RESTING" which refers to Beethoven's. A pronoun cant refer to a possessive pronoun. So eliminate the choices

So, we left with two choices. In that, C is more indirect way and try to use active way in the modifier
C: "he was buried" & his resting place lies
E: it is direct in second clause and use the who clause to give info
So, E is the answer
