Answer:
C
Explanation:
The strongest support for Charles' claim that Cordelia is fortunate that the Duke of Burgundy refuses to marry her is option C. Lear warns Burgundy that Cordelia's "price is fall'n" but that she can still marry Burgundy. As France says, Cordelia is "most rich, being poor" and "most lov'd, despis'd". Cordelia herself recognizes Burgundy's goals, saying that "respects of fortune are his love", in other words, his own wealth means more to him than she does. This passage provides the most direct evidence of Burgundy's concern with enriching himself and his lack of genuine interest in pleasing Cordelia.
