Venga conmigo. Correct Incorrect
Answer : Correct.
Explanation : The implicit subject in this sentence is "Usted", the formal second person in Spanish, so the entire sentence would be "Venga usted conmigo", that is the imperative mode of the verb "venir", that it is admitted without a explicit subject, because in Spanish, the conjugation form, indicates the subject. "¡Venga conmigo!" that means "You, come with me! "
That is a command.
