Please explain

@Steph, Happy to help. This question is very open-ended, so it's hard for us to have a sense of what to anticipate. This means that we should go through each of the answer choices and compare them with our understanding of the passage. In reading (A), we see that it's referred to in the fourth paragraph. There, we find out in lines 51-54 that contingency-fee agreements "shift the risk of not recovering these costs, and of not obtaining a damages award that will pay their lawyer's fees, from the client to the lawyer." This is precisely what (A) says, so it's the correct answer. Does this make sense? Let us know if you have any questions!

Hi can you please explain why B is wrong given that it conveys the same idea as line 17-20

Hi, (B) is wrong because if we take a look at those lines you mentioned, we see that they don't mention how much lawyers "deserve" to get paid, the crucial point of (B). Thus, the comparison made here isn't quite right. Hope this helps.
