Respuesta :
The correct answer is A: Character vs. himself.
This excerpt belongs to the short story "The Scarlet Ibis" written by James Hurst and published in 1960.
In this passage, the main character/narrator is feeling embarrassed because he has helped his brother only for selfish reasons. It is considered as character vs himself because he feels ashamed of himself and of the pride he is driven by. The character himself regrets his decisions.
