Option C is the correct answer because "to deter" means to discourage (someone) from doing something by instilling doubt or fear of the consequences, and "heed" means to listen to or pay attention to, so it is correct because that means that Nabeesa didn't listen to the criticism and was not bothered and went on.
Option A is incorrect because "warning" means an a statement made as a caution of danger, but in the statement the speaker only talks about criticism.
Option B is incorrect because "mind" means a person's ability to think and reason out, which is incorrect here because "paid no mind" is incorrect, it would be correct if it was simply, "did not mind".
Option D is incorrect because "hurt" means to be physically or emotionally damaged, which is incorrect here because a pron gets hurt, he does not " pay hurt".
