The assignment in the Constitution of lawmaking, law-enforcing, and law-interpreting functions to the legislative, executive, and judicial branches, respectively, is known as which of the following?

A) The supremacy clause
B) Inherent powers
C) Direct democracy
D) The implied powers clause
E) Separation of powers

The assignment of lawmaking to the legislative branch, law-enforcing to the executive branch, and law-interpreting to the judicial branch is known as separation of powers. Therefore, choice E is the correct answer. The supremacy clause refers to the Constitution being the supreme law of the land, inherent powers refer to powers that are not explicitly stated in the Constitution but are necessary for a government to carry out its duties, direct democracy refers to a system in which citizens can directly vote on laws, and the implied powers clause refers to the necessary and proper clause that allows Congress to carry out its enumerated powers.
