(mc)what is true about state laws?

1. state laws can infringe upon the rights given by the us constitution.
2. state laws cannot give citizens more freedoms or rights than those given in the us constitution.
3. state laws can be harsher than federal laws, requiring more responsibility from citizens.
4. all of the above are true.

I believe the answer is three. One is obviously not true, therefore eliminating 4 as well. As for option 2, in the Constitution, one of the amendments in the Bill of Rights declares that just because a right may not be listed does not mean that it does not exist. That means that that option is not true either, leaving us with option 3.
