Answer:
A
Explanation:
“Amateurs” implies/connotes an inexperienced, bad at everything, person.
Basically, being called an amateur is bad.
Obie thinks the other sale-men are bad at their jobs, and that he himself is better than them. It is obvious he does not like them and thinks of them as less, so he is not nostalgic, hopeful, and especially not approving. The only choice that would make sense is being disappointed, because he thinks that they are inexperienced and useless.
