The system that maintains the separation of powers among the branches of the federal government is called checks and balances.
Answer: Option C
Step-by-step explanation:
For the smooth working of the government, it is essential that the powers are distributed effectively among its different branches. This separation of power ensures that no branch abuses the power and each one keeps a check on the other.
The system of checks & balances was enshrined in the U.S. Constitution to provide a safeguard against the tyranny as it ensures that the power is divided among the different branches and they keep check on each other, hence, avoiding the accumulation of power.
