Answer: The correct answer is option B) Who are the main characters in this novel?
Explanation:
Interrogative sentences are useful for asking direct questions. These sentences have a specific grammar structure and differ from indicative or negative sentences.
Interrogative sentences start with an interrogative pronoun (what, where, when, who, why) when the objective is to gather information. We also can find yes/no questions that start with an auxiliary verb.
All interrogative sentences finish with a question mark (?).
