The Declaration of Independence states that if the government fails in its obligations to protect the people's rights to life, liberty and property, the people have the right to overthrow the government.

The social contract is the idea that government has a duty to protect the people’s rights in exchange for their consent to be governed. If the government fails to meet that duty, the people may change or overthrow it. That makes “social contract” the correct choice; unalienable rights are the rights themselves, not the agreement between people and government.
