Final answer:
The Founding Fathers included an amendment process in the Constitution to ensure it could adapt with the changing times and needs of the nation, while also making its alteration a deliberately difficult task to maintain stability.
Step-by-step explanation:
The Founding Fathers created a process for amending the Constitution primarily C) to accommodate future changes and adaptations in the country's laws. Known as the Amendment Process, this was established to ensure that the Constitution could adapt to the nation's changing needs, reflect changing times, and address concerns or structural elements that were not initially anticipated.
James Madison, following Article V of the Constitution, was key in drafting nineteen potential changes, which eventually resulted in the Bill of Rights.
The process requires a two-thirds majority in both the House and the Senate, followed by ratification from three-quarters of state legislatures or ratifying conventions to adopt an amendment, exemplifying the flexibility and foresight of the Founding Fathers to sustain the new government.
