Answer:
The answer is C.the Establishment Clause and D: social contract theory
Step-by-step explanation:
Establishment clause or the religious establishment clause prevents the US Congress from passing any laws that would force the implementation of one belief over another and protects the right to free religion.
What should be remembered is that Establishment clause is strengthened by the the Free Exercise Clause which states that the government should not pass any law that affects the exercise of any religion.
social contract theory advocates that the governments are formed by people for their protection and benefit and because of that, the government has the authority over the individual and that the government should rule with the consent of those who formed it. The theory was emphasized by John Locke during the Enlightenment age.
