The correct answer is D) They knew that the Constitution would have to be changed over time.
When the U.S. Constitution was created, the creators included an amendment process because they knew that the Constitution would have to be changed over time.
This was a smart decision the founding fathers of the United States made to allow future generations to consider the possibility of adjusting some articles of the US Constitution to adapt them to modern times and circumstances.
Prominent Americans such as Thomas Jefferson, James Madison, Alexander Hamilton, or Benjamin Franklin, had the vision to understand that the country would face different scenarios in the future that required constitutional modifications or adjustments. That is why they included the complicated amendment process.
