The correct answer is: D. No improvement
The sentence “The doctor said that there was no cause of anxiety” is grammatically correct and conveys the intended meaning clearly. The word “cause” is used correctly to refer to the reason or explanation for something. The preposition “of” is also used correctly to indicate that the cause is related to anxiety.
The other options are incorrect because they do not make sense in the context of the sentence. The word “to” is used to indicate a purpose or goal, but there is no purpose or goal mentioned in the sentence. The word “for” is used to indicate a reason or explanation, but the sentence already has a reason or explanation. The word “with” is used to indicate a relationship or association, but there is no relationship or association mentioned in the sentence.
