The power to regulate intrastate trade is reserved for the states as it falls within their jurisdiction to control trade and commerce that occurs solely within their borders. The U.S. Constitution, particularly the Commerce Clause, grants the federal government the authority to regulate interstate commerce, which involves trade between states, but leaves intrastate commerce to state regulation. This means states can set their laws and policies affecting commerce that does not cross state lines, allowing them to cater specifically to local needs and economies.

In contrast, the other options involve powers that the Constitution reserves for the federal government. Regulating international trade and establishing military alliances are both powers explicitly granted to the federal government, enabling it to manage relationships with other nations effectively. Coining money is also a power exclusive to the federal government, designed to maintain a uniform currency and economic stability across the nation. Thus, identifying the regulation of intrastate trade as a state power aligns perfectly with the division of responsibilities outlined in the Constitution.
