Atransitive verb with a direct object is in the voice.

Hello. Well, voice in the English language refers to either passive or active. So if your sentence is in the active voice (for example. He is writing a book - the verb write is transitive, "a book" is a direct object) your answer would be active voice. And transitive verbs are the only ones that can form passive voice (for example: He is writing a book - A book is being written).
