Answer Details

The best word to complete the sentence is "leave." The sentence is in the imperative form, which means it is a command or a suggestion. The word "leave" is in the present tense and fits well with the urgency of the situation. "Left" is in the past tense and doesn't make sense in this context. "Be leaving" is in the present continuous tense and sounds awkward. "To leave" is an infinitive and doesn't fit grammatically as a command or suggestion.
