From the words or group of words lettered A to D, choose the one that best completes the sentence.
It is time we ... for the party.
Answer Details
The best option that completes the sentence is "left."
The sentence is in the past tense, which means the action has already happened. The word "left" is the past tense of "leave" and fits the context of the sentence.
The other options are incorrect because they do not match the tense of the sentence. "Leave" is in the present tense, "have to leave" is in the present perfect tense, and "will leave" is in the future tense.
