I'll try my best to explain why C is incorrect.

Autism is a disease in which a child may be severely retarded, have problems speaking -- Tense wise, if austism is a disease, then a child has a problem breathing

Moreover --> and also bizarre behavior is redundant

Hope this helps!

(A) Autism, where a child may be severely retarded, have problems speaking, and exhibit bizarre behavior, occur -------- "Where" is used for places. "Occur" should be "Occurs" since Autism is singular

(B) Autism, which manifests itself in children in severe retardation, speech problems and bizarre behavior, occurs -------------- Correct answer since the modifier is set off by commas and "Autism occurs .... " is correct sentence

(C) Autism is a disease in which a child may be severely retarded, have problems speaking and also bizarre behavior and it occurs --- Issue with parallelism

(D) A disease causing severe retardation, speech problems, and behavior may be bizarre, is autism which occurs ------------ problem with parallelism and sentence structure. There is no need to invert the sentence structure

(E) Autism, causing severe retardation, speech problems and bizarre behavior, and occurring -------- There is no working verb in this sentence and hence it is a fragment

The sentence has problems with structure and parallelism.

Option B gets both of them right and is the correct answer IMO.

The first and most important issue that can be seen here in the prompt is of Subject - Verb agreement.

Subject 'Autism' is singular but the verb 'occur' is plural. So definitely wrong.

Incorrect due to above stated reasons.

SajjadAhmad wrote:
(B) Autism, which manifests itself in children in severe retardation, speech problems and bizarre behavior, occurs


Though not the biggest fan of this answer because of the phrase 'children in severe' but it is the best answer out of the lot. Hence Correct

SajjadAhmad wrote:
(C) Autism is a disease in which a child may be severely retarded, have problems speaking and also bizarre behavior and it occurs


This should be rejected because of change in meaning as here Autism is being stated as a disease and that is not what was mentioned anywhere in the prompt.
Apart from this, 'it' pronoun is ambiguous as we are not able to apprehend to which noun in specifically is it calling back to.Hence because of these reasons this option is Incorrect

SajjadAhmad wrote:
(D) A disease causing severe retardation, speech problems, and behavior may be bizarre, is autism which occurs


Same disease related problem as in C. Other errors are also there such as 'A disease ...... is autism'. This seems to be a very awkward construction of a sentence. Apart from this, we should also have 'that' instead of 'which'. So because of these reasons the option is incorrect

SajjadAhmad wrote:
(E) Autism, causing severe retardation, speech problems and bizarre behavior, and occurring


Incorrect as the subject 'Autism' is not followed by a verb, which is expected here. Case of Missing Verb

Hence B
