Answer:
D) So that many of the noble knights were afraid to answer, and all were struck by his voice and stayed still.
Step-by-step explanation:
Sir Gawain and the Green Knight is a late 14th-century Middle English chivalric romance and one of the best-known stories about the legendary King Arthur.
It tells about how Sir Gawain, a knight of King Arthur's Round Table, accepts a challenge from a mysterious Green Knight, who dares any knight to strike him if he will accept a return blow in a year and a day. Gawain accepts and beheads him. At the end, when the Green Knight is supposed to return the favor, he only lightly wounds Gawain and reveals that he is in fact a lord transformed by magic and that this was all a test designed by Morgan le Fay, Arthur's sister, who wanted to test Arthur's knights.
The given excerpt shows the encounter between Arthur's knights and the Green knight. They were staring at him and crept closer to him because they were curious, and since they had seen nothing like that before, they thought it might be a phantom or magic. We can see that they were also intimidated by the fact that they were afraid to answer and froze.
Thus, the correct answer is D.
