Answer:
B. can have a new law approved in a referendum.
Step-by-step explanation:
A federal law making process requires the proposed law or bill to pass through the two legislative chambers for approval and also requires an executive such as the president to approve the law.
However, in state law making process, new laws can be passed (effective only in that state) by referendum.
*Referendum is a vote by electorates about a proposal and they have to tick "yes" or "no".
