Final answer:
Wickham accuses Darcy of disgracing his father's memory by neglecting moral and societal obligations, aiming particularly at the unfulfilled promise of an ecclesiastical living. Option C.
Step-by-step explanation:
The character George Wickham in Jane Austen's Pride and Prejudice believes that Fitzwilliam Darcy is disgracing the memory of his father by not fulfilling the moral and social duties expected of a gentleman, especially in regards to the promised living for Wickham himself.
As in many works of the time, a gentleman inheriting his father's estate was expected not only to maintain but to elevate his family's reputation and prosperity, showing gratitude toward the benefactors and caretakers of his upbringing, and adhering to societal norms of decency and benefaction.
Darcy's perceived failure in these areas, especially his decision not to grant Wickham an ecclesiastical living as allegedly promised by the late Mr. Darcy, is construed by Wickham as a betrayal to the late Mr. Darcy's intentions...
Wickham spreads the story that Darcy has hurt the laws of moral duty and challenged socially accepted norms by not bestowing upon him the living, which Wickham claims was promised to him by Darcy's father as a token of his affection.
This promise, Wickham suggests, was like an agreement between the late Mr. Darcy and himself, as the legacy was expected to be passed down and respected. Darcy's actions, therefore, are painted as both personally hurtful to Wickham and as a broader indication of Darcy's disrespect to his father’s memory.
So Option C.
