Good question....
But I managed to eliminate all but A, B and E.
Now When Negated A, I found it did not help to destroy or affect the conclusion in a negative manner.Actually, Interfernce or It was federal govt that created the economic stability...so option A bit strengthens the conclusion.
And E...When negated New deal did not affect the market...in noway affecting the conclusion. Conclusion is about fed govt....and market...so we can eliminate.
But B when negated....does not allows the conclusion to stand on its own....
"Federal regulation is not an emergency measure....and should not be temporary" Actually makes the conclusion unable to stand on its own as it says"Fed regulation had become hindrance fr economic stability"
Consider Kudos If my post helps!!!
