Final answer:
The U.S. Constitution enforces limited government through a system of checks and balances, protection of individual rights in the Bill of Rights, and granting Congress the power to declare war.
Step-by-step explanation:
The concept of limited government in the United States Constitution ensures that no entity or individual has absolute power, and it protects the freedoms and rights of the citizens.
Illustrations of how the Constitution implemented limited government include: A) A system of checks and balances among the three branches of government, C) Protection of individual rights in the Bill of Rights, and D) The power to declare war granted solely to Congress. Option B, the establishment of a monarchy, does not illustrate limited government and is, in fact, contrary to the principles of the Constitution.
Checks and balances are evident as the branches can regulate each other's powers, ensuring that no single branch overwhelms the others. This is underscored by judicial review, the ability of the Supreme Court to deem laws unconstitutional, checks on the President such as veto override and impeachment, and the Senate's confirmation of judicial appointments.
The protection of individual rights is central to limited government, which is prominently outlined in the Bill of Rights, securing liberties like freedom of speech, the right to a fair trial, and protection against unreasonable search and seizure. Lastly, giving Congress, not the President, the sole power to declare war prevents the executive branch from unilaterally involving the nation in conflicts.
