The presidential form of government operates on which of the following principle ?

Correct option is D

The Presidential form of government operates on the Doctrine of Separation of Powers, wherein the executive, legislative, and judicial branches of the government are separate and independent. This principle ensures that no branch interferes in the functioning of the others, thus maintaining a system of checks and balances. The United States of America is the best example of a presidential system.

1. In this system, the President is both the Head of State and the Head of Government.
2. The President is elected independently of the legislature.
3. The executive does not rely on the confidence of the legislature to stay in office.
4. The principle was proposed by Montesquieu in his book "The Spirit of Laws."
5. The system prevents the concentration of power in a single authority.
