Answer:
The emotion that best describes Farquhar's feelings at the end of the passage is C: Determination.
Step-by-step explanation:
At the end of the excerpt, the speaker analyzes the ways of dying, and he says that to be hanged and drowned wouldn't be "so bad". On the other hand, he believes that to be shot wouldn't be "fair", and he chooses not to be shot with determination. He surely doesn't want to live that situation and makes the choice not to do it -as if it were possible to decide what the future brings all the time.
