A social contract is an agreement between <u>the ruled and their rulers or the government and the people.</u>
In political philosophy the concept of the social contract was first fully developed by the English philosopher Thomas Hobbes in his book named "Leviathan: The Matter, Form, and Power of a Commonwealth, Ecclesiastical and Civil" (1651).
The author defined a social contract as an agreement between the ruled and their rulers, in which all individuals in a society cede their natural rights (life, liberty, property, etc.) to an absolute government, even meaning that individuals would have to accept abuses of power. Through the contract people could live better and maintain peace, receive protection and avoid conflict by the establishment of a civil society.

Not D - Muslims constantly follow the Quran because it is their holy book, much like a Christian with the Bible or a Jew with the Torah.
Hope this helped!
