An English reading problem. Jokes about doctors imply that in the eyes of nurses, they are B? .

This reading comprehension is a joke I heard from a nurse. This is a satire on the doctor's self-righteousness

Among the four options, A is rude to newcomers, B is self-righteous, C deserves some privileges, and D is busy at lunch time.

C and d are obviously incorrect. This is just a joke. The content of the joke is about how doctors are rude to new people, but the problem is implicit, so we should think more about it. What does this joke mean? It's impolite to new people. The last sentence: Yes, that's God, replied the camel, but sometimes he thinks he is a doctor. That means nurses don't like doctors' self-righteousness. So choose B.
