Answer:
b. Admit your mistakes and move on.
Step-by-step explanation:
The story of "Sir Gawain and the Green Knight" is an Arthurian tale that revolves around the story of a brave knight of King Arthur's court and the chivalry and bravery that he embodies. The tale concerns the successful defending of the king's reputation by his trusted knight Sir Gawain against the menacing Green Knight.
After the Green Knight challenges the men in King Arthur's court, and he had been dealt three strikes by Sir Gawain, it was time for him to reciprocate the strike. Sir Gawain kept his promise and returned to fulfil his promise, letting the knight strike him thrice too. But the first two blows didn't hit him, and the third merely cut his skin. When the promise was fulfilled and Sir Gawain challenged him for an open duel, the Green Knight revealed his true intention- to see for himself how the men in King Arthur's court are. At the end, he did found true that Sir Gawain is indeed a true and brave man, and kept his promises. Though Sir Gawain failed to reveal about the green girdle that the Green Knight's wife had given to him, the Green Knight forgave him, telling him that it was his idea to test him. He told Sir Gawain to admit his mistakes and then move on,
"I hold it happily made whole, the harm that I had; You are confessed so clean, cleared of your faults, and have done penance plain at the point of my blade, I hold you absolved of that sin, as pure and as clean, as though you were never at fault since first you were born."
Thus, the correct answer is option b.
