Final answer:
Each of the 50 states in the United States has its own governor, state constitution, and state legislative body, establishing a structure that provides each state with self-governance under the federal system. The correct option is 1.
Step-by-step explanation:
True: Each one of the 50 states in the United States does, in fact, have its own governor, state constitution, and state legislative body. Governors play a vital role in the state governments as the head of the state executive branch. They are often called upon to work with their respective state legislatures during the lawmaking process, serve as the head of their political party within the state, and act as chief spokespersons and crisis managers.
The primary functions of state legislatures include lawmaking, constituency service, and oversight. Each state also has a constitution that lays out the fundamental principles and framework for their government. Therefore, this structure allows each state to govern itself while still remaining a part of the federal system of the United States.
