Answer:
B) Fright
Explanation:
If the hairs on his arm 'stood up' then he's emphasizing that he might have gotten a shiver. If you feel excitement, you won't feel a shiver. If you're trying to say 'pain', then you could feel pain. If you were surprised, then you might feel excitement or shocked, which wouldn't cause you to say 'my hairs on my arms stood up'. Therefore, the option left is b) fright. If you feel frightened, then you might feel like something like that happened.
