Why are there three branches of government?

The existence of three branches of government is fundamentally rooted in the principle of separation of powers, a central tenet designed to prevent any single entity from gaining excessive authority. This system splits governmental responsibilities among the legislative, executive, and judicial branches, each with distinct powers and functions. By doing so, it creates a system of checks and balances that ensures no one branch can dominate the others. This framework is crucial for maintaining a balanced government, protecting individual liberties, and allowing for accountability within the system.

While the other options may present valid points regarding government operations or constitutional mandates, they do not encapsulate the primary reason for the tripartite structure as effectively as the prevention of concentrated power.
