I was down to (A) and (C).
I see that the correct answer (C) is supported by lines 44-49 + the fact in the beginning of the passage that anarchists believe they don't have a moral duty to obey gov. laws (14-15).
However, I like (A). Is it wrong because it's too far of a logical leap to say that people are subject to more moral obligations than what is believed to be the case? Reading the last paragraph and about all these natural-law type moral obligations made me think it wasn't too much of a stretch to pick (A).
