Which statement best describes the concept of separation of powers?

• A. One branch holds all power.
• B. The Supreme Court decides what each branch can do.
• C. The President can veto all laws.
• D. Each branch has distinct, constitutionally assigned powers.

Answer: (D)

Separating powers means no one person or group holds all government authority; authority is divided among three branches so each has its own job defined in the Constitution. The best description is that each branch has distinct, constitutionally assigned powers, which means the powers are specifically granted and limited to that branch—Congress makes laws, the President enforces them, and the courts interpret them. This setup creates checks and balances so no single branch can act without oversight from the others.

Think of it this way: giving each branch its own responsibilities helps prevent the abuse of power and keeps the system balanced. The idea that one branch holds all power describes tyranny, which the separation of powers tries to avoid. The notion that the Supreme Court decides what each branch can do oversteps the division of roles; lawmaking, enforcing, and interpreting laws remain separate responsibilities. And the idea that the President can veto all laws ignores the ongoing legislative process and the checks and balances that allow Congress to override vetoes and for courts to review actions.
