Which line from the text most clearly conveys the authors main focus

Which sentence correctly uses a normative case pronoun

Can someone explain this to me clearly plz

The author most likely uses the word monstrous rather than the word “unpleasant” because it has a more positive connotation than the word “unpleasant.” a more negative connotation than the word “unpleasant.” a more neutral connotation than the word “unpleasant.” almost the same connotation as the word “unpleasant.”
