Final answer:
The correct matches between the philosophers and their philosophies are Voltaire for the view on religion, Thomas Hobbes on the social agreement to prevent mutual harm, Jean Jacques Rousseau on exchanging freedoms for security, and William Blackstone on natural law being divine. Hence, choice 'd. 1c, 2b, 3a, 4d' is the correct one.
Step-by-step explanation:
