Answer:
The code of chivalry followed by knights in the Middle Ages entailed loyalty to God, the king, and one's lady. A knight was expected to show courage and courtesy and be true to his word.
Sir Gawain upholds the code throughout the plot of the narrative. Gawain’s actions throughout the narrative give evidence that he is a true knight as his chivalry is tested many times in the story.
He shows his loyalty when he steps forward to accept the Green Knight’s challenge in the place of Arthur. His courage and courtesy are reflected in his actions. He is a true knight, but he has his human weakness, as is seen when he falls prey to the temptations of Bertilak’s wife.
He does not tell Bertilak about the green girdle given by his wife to help him survive mortal attacks. However, he does not hide this fact, and he wears a green girdle as a constant reminder of his shame.

The correct answer is C. uses evidence to prove one idea is better than another.
If you want to make an effective argument and persuade the readers/listeners into believing you, you will need to present them with concrete evidence. If you just use you emotions (such as anger, or sadness) or opinions, you are probably not going to make them trust you. It may happen that your emotions are misplaced or that other people don't share them, or that your opinions don't resonate with your audience. This is why relying on evidence is the way to go.
