The correct answer is:
D. It suggests that although Arthur wants Merlin’s advice on who to marry, Arthur does not listen to his concerns.
The excerpt illustrates that while Merlin acknowledges Arthur's love for a certain woman, he expresses a desire for Arthur to choose someone who is both beautiful and virtuous. However, Arthur's strong feelings for the woman make him unwilling to consider other options, indicating a conflict between his emotions and the advice given to him.
