Hi @SoniaDanielle, in most situations, laws and regulations can be used interchangeably!
If this question had both regulatory risk and legislative risk as options, it would be much more challenging.
It feels like you understand the concepts so my advice is to continue with other topics, but here are two examples that might help clarify:
Regulatory risk: The US government is discussing passing a law that requires Apple to allow the US government access to encrypted messages between users.
Legislative risk: The US government is discussing passing a law that requires Apple to pay an additional 25% tax on purchases on semiconductors and materials manufactured overseas.
Many concepts can often apply in these situations, and it’s important to pick the best choice of the given options, without worrying about technicalities!
