Final answer:
The necessary and proper clause in the United States Constitution has actually expanded the power of the national government.
Step-by-step explanation:
The necessary and proper clause in the United States Constitution, also known as the elastic clause, grants Congress the power to make laws that are necessary and proper for carrying out its enumerated powers. This clause has actually expanded the power of the national government, rather than limiting it. It has been interpreted broadly by the Supreme Court, allowing Congress to pass legislation that may not be explicitly stated in the Constitution but is necessary to carry out its enumerated powers. Therefore, the statement that the necessary and proper clause has limited the power of the national government is False.
