Ruling out A, C and E were straight forward as many posts have mentioned. I got stuck between B and D.

The way I looked at the question to understand the deeper meaning of the problem:

XYZ (representing the subject of this sentence) THAT HAS................AND......WITH.....THAT is NOT PARALLEL.
Why?
On both sides of the AND should be talking about the same subject which is XYZ. But when we use WITH A CAUSE, THAT is describing the CAUSE rather than XYZ.

In Option, B where it goes THAT (HAS..............AND......WHOSE) is parallel and both describe the XYZ subject correctly.

How can it be B. I thought whose can only be used to refer to a person.

The sudden outbreak of a devastating disease that has not been reported before and which is unknown in cause is a rarity in modern medicine.

Modifier : that has not... and <need some pronoun - that or whose>

(A) which is unknown in cause - wrong absurd structure and meaning issus
(B) whose cause is unknown - Correct
(C) is unknown as to its cause - wrong parallelism
(D) with a cause that is unknown - paralllelism issue
(E) unknown in cause - parallelism

Hi,
Question -

The sudden outbreak of a devastating disease that has not been reported before and which is unknown in cause is a rarity in modern medicine.

(A) which is unknown in cause
(B) whose cause is unknown
(C) is unknown as to its cause
(D) with a cause that is unknown
(E) unknown in cause

A) -> which doesnot work well here because it is suppose to modify immediate.
C) -> Wordy, also 'is unknown as to its cause' -> ambiguous
D) -> with a cause => doesnot make sense
E) -> requires a supporting verb -> say 'is unknown in cause' is better.
B) -> 'whose' can refer to living as well as non-living and is appropriately placed here to refer to the disease that has been modified in first clause.

Cheers

To maintain parallelism, that (clause) & which/whose (clause) .
Options left are A&B.
According to GMAT, "whose" can modify either people or things. Sounds more clear ; concise.

B.

Dear Friends !!

Pl check OGs, GMAT does not consider whose, which, what, and alike parallel to that. Only that to that, which to which, when to when.

Thanks

The sudden outbreak of a devastating disease that has not been reported before and which is unknown in cause is a rarity in modern medicine.

(A) which is unknown in cause
"that" should be used instead of "which"

(B) whose cause is unknown

(C) is unknown as to its cause
make the sentence run-on

(D) with a cause that is unknown
not parrallel

(E) unknown in cause
not parrallel

Longman contemporary dictionary says:
whose used to show the relationship between a person or "thing" that belongs to that person or thing
so B is correct

Request you not to write your queries/answers/opinions in question window. It prevents ppl from analysing the question. The

whole purpose of GMAT Club forum goes wasted by doing

It is NOT necessary that when two relative clauses are made parrallel, the relative pronouns that introduce the clauses be the same. It is alright to use one relative pronoun ("that") to introduce one of the clauses and another relative pronoun ("whose") to introduce the other relative clause. In Option B, the following relative clauses are parallel:

1. that has not been reported before
AND
2. whose cause is unknown

,both referring to "disease".
