Which of the following is typically found in state constitutions?

State constitutions often include a Bill of Rights and a separation of powers as fundamental components. The Bill of Rights guarantees individual liberties and rights to citizens within the state, much like the federal Bill of Rights, though specifics may vary across different states. This inclusion reflects the commitment to protecting citizens' freedoms and outlines what the government cannot do against its people.

The separation of powers is another key principle typically found in state constitutions. It establishes distinct branches of government—executive, legislative, and judicial—ensuring that no single branch wields excessive power. This structure is designed to create a system of checks and balances that promotes accountability and prevents tyranny.

In contrast, the other options do not accurately reflect standard components of state constitutions. While some might include executive powers and local rules, these are not comprehensive elements across all state constitutions. State constitutions are unlikely to omit taxation regulations, as these provisions are essential for the functioning of state governments. Also, international treaties are generally the purview of the federal government and are not typically included in state constitutions.
