Which of the following powers is explicitly denied to the states?

The power to coin money is explicitly denied to the states by the U.S. Constitution. Article I, Section 10 of the Constitution specifies that no state shall enter into any treaty, alliance, or confederation; grant letters of marquee and reprisal; coin money; emit bills of credit; or make anything but gold and silver coin a tender in payment of debts. This provision is crucial to maintaining a uniform currency across the nation and preventing states from creating their own money, which could lead to confusion and instability in the economy.

The other options fall within the powers that states can typically exercise. States have the authority to regulate intrastate commerce, establish local governments, and conduct elections. These powers are generally reserved to the states, allowing them to manage their own affairs and governance within their boundaries.
