C)what she is saying
D)what is she saying

Answer 1

Hint: The sentence is a yes or no interrogative sentence.

Complete step-by-step answer:

 The given blank when filled makes the sentence a yes or no interrogative sentence. It is interrogative as the question starts with can and ends with a question mark. It further falls into the yes or no category as the answer of the question, from the way it is framed, is expected to be yes or no.
The sentence order for such a sentence is auxiliary verb + subject + verb.
It must also be noted that the given phrase is joining two parts of a sentence together and hence, it needs a conjunction.
With these points in mind, let us take a look at the options.
Option A is incorrect as it does not have a conjunction.
Option B and D is incorrect as it does not follow the given sentence order.
The correct answer is Option C, what she is saying as it has a conjunction and follows the sentence order.

Note: It is essential to know the sentence order, also called the syntax. Once learned, the order of the sentence will come to you naturally, while answering.
