Interrogative = question

You are correct! The interrogative sentence is B. "What time will you be home tonight?" An interrogative sentence is a sentence that asks a question. To determine if a sentence is interrogative or not, you can look for question words like who, what, where, when, why, or how. In this case, the word "what" is used to form a question, making sentence B an interrogative sentence.
