A) the freedom of religion  

Explanation:

Voltaire is one of the great names of the Enlightenment and his writings are characterized by irony, vividness and polemic, especially against injustice and superstition. He is a deistic philosopher, that is, he admits the existence of God, but denies to any church the right to be his representative. He defends what he calls the natural religion and sees God as a being distant from the world, responsible only for his creation and who does not interfere in the history of men. In addition, it is considered as skeptical, secular and anticlerical.

In some of his works he defends political freedom and criticizes religious intolerance. Based on this, the concept of religious tolerance is included in the US Constitution
