Hi! :)
The word rectify means to correct something or put it right, so it could replace the word correct in option D.
Hope this helps!
Answer:
Marcus Junius Brutus
Explanation:
Brutus eventually came to oppose Caesar and fought on the side of the Optimizes faction, led by Pompey, against Caesar's forces in the Civil War (49–45 BC). Pompey was defeated at the Battle of Pharsalus in 48 BC, after which Brutus surrendered to Caesar, who granted him amnesty.
Well, you don't exactly comment per se. You click "answer" or go to someone else's answer and click reply (not sure the exact labelling but it's something along those lines).
Edit: It says "add your comment to this answer here", not "reply."
