It's about time we _________ - it's nearly midnight
-
leave
-
to leave
-
left
-
leaves
C
Correct answer
Explanation
The subjunctive-like structure 'It's about time' is followed by a subject and a past simple verb to express a present or future desire. Therefore, 'left' is the correct form to show that the action should happen now. Other verb forms like 'leave' or 'to leave' do not fit this grammatical pattern.
