Final answer:
The Constitution sets up the government, defines its powers, and protects the basic rights of Americans.
Step-by-step explanation:
The Constitution is a document that sets up the government and defines its powers and limitations. It does not establish a king, as in option A, but instead establishes a system of government based on principles outlined in the Constitution.
One of the key functions of the Constitution is to protect the basic rights of Americans. These rights, such as freedom of speech, religion, and the right to a fair trial, are outlined in the Constitution's Bill of Rights.
In summary, the Constitution sets up the government, defines its powers, and protects the basic rights of Americans.
