Why did the constitutional congress decide to create three branches of our government? a. they felt that three branches would be enough to overpower the individual states' governments. b. the u. s. government was so big that it had to be divided for organizational purposes. c. the three-branch system established a strong central government without giving too much power to any one group. d. they modeled the government after the government of england.

C. The three-branch system established a strong central government without giving too much power to any one group.

The colonists were used to a strong central government, like England's, but they were afraid of tyranny, like with England.  Once they had independence, they created a strong government because it was their custom, but they instituted a system of checks and balances (with three branches) to prevent any one person or group of people from gaining too much power.

Hope this helps!!

i would say your answer is a)

sorry if im wrong
