What powers are denied to the states by the U.S. Constitution that also apply to Missouri?

The correct choice identifies specific powers that the U.S. Constitution prohibits states from exercising, directly aligning with the constraints placed on Missouri as well. The Constitution explicitly denies states the authority to enter into treaties with foreign nations, coin money, and impair the obligation of contracts. These restrictions aim to maintain a unified federal structure, prevent conflicts between states and foreign entities, and protect the sanctity of contracts which are fundamental to economic stability.

While the other options include activities relevant to state functions, they do not encapsulate the constitutional prohibitions that apply universally to all states, including Missouri. For example, states are typically empowered to issue bonds, establish public schools, and regulate commerce within their borders, making those options less aligned with the specific powers denied by the U.S. Constitution. The focus of this question is on powers outright barred to states, reinforcing the significance of maintaining federal authority and ensuring that states do not engage in actions that could undermine national interests or economic integrity.
