A) They feared a government with unlimited power.
Step-by-step explanation:
A constitution can be defined as a set of written laws and principles which is typically used to determine the power and authority of the government, as well as guarantee the fundamental rights of its citizens.
The Federalists refers to a group of people who were keenly interested in the ratification of the federal constitution of the United States of America in 1787. They unanimously believed and agreed that the Articles of Confederation wasn't adequate or sufficient enough to enhance good governance and serve the needs of the United States of America and as such required a new government having greater powers at the national level.
The framers of the U.S. Constitution included the concepts of federalism, checks, and balances, and separation of powers because they feared a government with unlimited power.
