Explanation:

The fragment C of the sentence is erroneous.

Here ‘demand’ is a singular countable noun and the helping verb ‘have’is a plural helping verb. As per the rules of grammar, we need to use a singular helping verb with a singular countable noun.

So ‘have’ should be replaced with ‘has’ in the sentence.

Therefore the correct sentence will be “With the rise in air pollution levels the demand for air purifiers in the market has increased significantly.”

Hence option C is the correct answer.
