From the words or group of words lettered A to D, choose the one that best completes the sentence. You were punished because you ...last week without permis...

Answer Details

The correct option is "ought not to have travelled". This is because the sentence is talking about a past action that was not allowed, and the speaker is explaining why the punishment was given. "Ought not to have travelled" indicates that the person should not have traveled last week without permission. The other options are not correct because they either indicate future actions (must not have traveled, will not have traveled) or present actions (ought not to travel), which do not fit the context of the sentence.
