Interesting question, because what you are being asked to do is pick out detail that supports an argument. You are not necessarily meant to tell what the argument is.
I think A is the answer.
- We learn why they are dirty through no fault of their own.
- We learn that pigs can get out of captivity, so they can problem solve.
C is an argument. It is not a detail.
B is a conclusion.
