Correct answer
Explanation
The phrase 'It is high time' is followed by the past subjunctive (unreal past) to express that something should have been done already. So 'It is high time that we did something' is correct - using 'did' (past tense form) to show urgency. Options like 'had done', 'would do', 'can do' change the meaning and are not standard with this construction.
