Which of the following sentences correctly expresses the necessity to execute the traitors?

Show Answers

The traitors ought to have been executed.They will execute the traitors.They ought to execute the traitors.They executed the traitors.

Option C is correct because it properly uses 'should' to indicate the necessity or obligation to shoot the traitors. Option A implies a past obligation that was not fulfilled, option B indicates a future action without obligation, and option D is a simple past statement without expressing necessity.
