The novella being referred to here is Joseph Conrad's Heart of Darkness. The second narrator refers to the main character of Marlow who is telling his story to an anonymous narrator upon board a ship sailing up the Congo river. The character that is being referred to as having died is Kurtz and by the end of the novella it has been over a year since Kurtz has died. The mourning character refers to Kurtz's fiancee or Kurtz's intended. At the end of the story Marlow returns to Brussels and decides to visit Kurtz's fiancee, they have a brief encounter, she says she will mourn Kurtz forever, Marlow tells her that his last words were of her and then the story comes to an end.
Though Donatello was a descendant of a branch of the important Bardi family, he was brought up in a more plebeian tradition than his older contemporary Lorenzo Ghiberti. Gifted with humanistic insight and a quality of will that were highly prized in the early Renaissance, Donatello revealed the inner life of his heroic subjects, memorable images which have conditioned our very conception of 15th-century Florence. Sharing neither Ghiberti's feeling for line nor Filippo Brunelleschi's interest in proportion, Donatello worked creatively with bronze, stone, and wood, impatient with surface refinements and anxious to explore the optical qualities he observed in the world about him. His later art, saturated with the spirit of Roman antiquity, is frequently disturbing in its immediacy as it attains a level of dramatic force hitherto unknown in Italian sculpture.
That would have to be C. Because most artists would not have a motive to do anything if they were not inspired to do so.
