Answer:
I would say that the description of the horseman's gaze helps the reader foreshadow that the father knows his final fate is at the bottom of the cliffs. The answer would be C.
Step-by-step explanation:
I chose C because, by reading the excerpt, the reader can understand that when looking into his son's eyes, the horseman sees compassion, but also bravery, so I think that what's going to happen is that the son will in fact shoot his father, but not without pity. I think he knows that's what he has to do and does it, but not without compassion for the relationship.
