Among the concepts you mentioned, the best explanation for the source of government power is popular sovereignty. Popular sovereignty is the idea that a government's power comes from the consent and authority of the people. This means that the authority of the government is derived from the will of the people they govern. It is based on the belief that individuals have the right to choose and participate in the formation of their government and that their government should work for the benefit of the people. The other concepts you mentioned, such as natural rights, limited government, and divine right of kings, all have different implications and do not directly explain the source of government power as clearly as popular sovereignty does.
