Your answer would most DEFINITELY be D., because it is already stated that "men", (all people), easily abuse the right of liberty and may not be given 100% trust, so the government must make sure to help protect the right from the selfishness of the people's use of that right. :)
The quote best reflects the idea of natural law. It says government power must be restricted to protect rights because people by nature are selfish.
Explanation:
The natural law is a philosophy holding that all humans beings are born with certain inalienable and universal rights (such as the right to freedom, life, privacy, etc.). Sentence number 4 reflects this idea because "liberty" is considered one of those inalienable and universal rights that no one, not even the government, can take away from people, and it also reflects the idea that government power must be restricted to protect those rights because people by nature are selfish: "all men having power ought to be mistrusted."
