Which of the following is true?

选项：

There is a single regulator for all insurance companies globally.

The National Association of Insurance Commissioners regulates all insurance companies in the U.S.

Insurance companies operating in the state of Maine are regulated by the state of Maine.

German insurance companies and Italian insurance companies are subject to different regulations.

解释：

C. Insurance companies are different from banks in that there are no global regulations. Regulations are enforced by the individual states in the U.S. The National Associa-tion of Insurance Commissioners is a forum for exchanging ideas but does not impose the regulations. In the Euro-pean Union there is a single set of regulations, so German and Italian insurance companies should be subject to the same regulations.
