Which term describes a sentence that asks for a reply?

The term that describes a sentence that asks for a reply is "interrogative sentence." Interrogative sentences are specifically structured to request information and typically begin with interrogative words such as "who," "what," "where," "when," "why," or "how." They often end with a question mark. This type of sentence engages the reader or listener, prompting them to provide an answer or response. By contrast, the other terms listed do not refer to sentences that pose questions: "intransitive verb" refers to a type of verb that does not require a direct object, "nominative case" pertains to grammatical case used for a subject of a verb, and "modifier" describes words that provide additional information about another word in a sentence.
