'that' refers to 'disorders' and hence 'create' must be in plural form. C and E are out.

'if' is used only for conditional sentences. A is out.
'Weather or not' is not a correct idiom. B is out.

D is the correct answer

Experts, please help clarify.

As per my understanding, "Prepositional phrases" do not contain subject and Verb with the exception of Quantitative prepositional phrases such as "Some of the.. ". "One of the ...", the number of ... etc.

Moreover the phrases "One of the" and "The number of" are always singular and the phrase "A number of .." is Plural.
So in the above case "Autism is one of the neurological disorders that create ..., 'that' refers to "one of the neurological disorders" which should have singular verb "creates" and not plural verb "create".
Hence Answer choice C should be correct.

"That" refers to "neurological disorders". There are many neurological disorders that create confusion - Autism is one of THEM.

A pronoun does not need to refer to a subject - it can refer to any noun, even if the noun is within a prepositional phrase.

I will add to what Sayantan has said.

"one of the neurological disorders that create confusion" - the article "the" is used to refer to specific things.

Since, "the" precedes "neurological disorders", we must specify "neurological disorders". i.e. "that create confusion". hence, plural verb.

However, look at this sentence -
"Minnesota is the only one of the contiguous forty-eight states that still has a sizable wolf population" - here "the only one ..." needs to be specified. Hence, the singular verb.

Also, objects of prepositions cannot be subjects of the main clause. They can very well be subjects of subordinate clauses.

I believe sentence structure is not right. There should have been a comma before and.
There are two clauses and they cannot be combined with coordinating conjunction "and" only.....use of comma is necessary....otherwise this "and" will point parallelism.

I agree with your point. There should be a comma before and. Other than this, everything else in D makes it THE BEST answer.

"One of the disorders that "- in the given phrase that refers to "disorders"
Therefore, it makes sense to use the verb in plural form -create
Since, we have already used a conditional whether, i guess there is no need for usage of not

Official solution from The Economist.

Answer : D

This answer choice correctly replaces if with whether since there is no condition present in the original sentence.
