This was a very interesting problem. Here's what I did:
There is a clear 3/2 split in the beginning of this problem. The legislation forbids something. So get rid of A/D.
Now we're looking at B, C, and E.
At first, I wanted to eliminate C because I don't like the "forbids to raise" phrase. I haven't studied this idiom. Then looking at B and E, these are basically the same sentence. I don't think I've seen that in a SC problem before. I mean, just think about the guys writing this test. It is pretty unlikely they would write a question with a choice like that. So I went back to C which I would probably chalk up to a guess as I haven't seen this idiom before. That's actually why I came to this forum, though!
Ultimately, this isn't that great of a question IMO. My take on the idioms thing is that there are far more productive things you can than put a lot of effort into than idioms. For instance, just having seen this problem before will now enable us all to choose the correct answer if we ever stumble upon "forbids to" again.
