The answer is B. The only explanation I can give is that A and C are wrong because the legislative, judicial, and executive branches all share power. As far as D goes, the states' own laws don't really affect each other so there is no need for the power to be shared among them. Anything outside of the state becomes federal.

I just took the test it is C:Natural disasters
The answer is most likely D. Refused aid to any nation at war. If the U.S. remained neutral, it would not have to worry about going to war/being attacked by a nation at war with another.
Hope this helps! Brainliest is always appreciated!
