The statement that best explains why the Framers may have included the elastic clause in the Constitution is:
• to ensure that Congress had sufficient powers to carry out the expressed powers.
The elastic clause, also known as the Necessary and Proper Clause, is found in Article I, Section 8 of the U.S. Constitution. It grants Congress the authority to make all laws that are necessary and proper for carrying out its enumerated powers, allowing flexibility in legislative authority.
