Answer:
The answer is d.
Step-by-step explanation:
The United States upholds the separation of powers between the Legislative, Executive and Judicial powers, which means that they operate as independent institutions. This entails that one branch is responsible has certain core functions, such as passing laws, and it cannot interfere in the core functions of another, such as adjudicating legal disputes. However, each branch of government provides checks and balances to the other branch in order to avoid abuse of power.
