The correct statement is: Diderot and Voltaire used reasoning rather than religion to explain the natural world.

Enlightenment thinkers like Diderot and Voltaire challenged religious structures by promoting the use of reason and rationality to understand and explain the natural world. They advocated for the pursuit of knowledge through scientific observation and experimentation, rejecting religious dogma and superstition as the basis for understanding the universe.

While Voltaire did have his own ideas about religion and state, including his belief that each state should only have one religion, it is important to note that Diderot disagreed with this perspective. Additionally, both Diderot and Voltaire did not believe that religion explained all natural phenomena, as they sought to separate scientific inquiry and religious beliefs.

Lastly, Diderot did not argue against freedom of religion causing problems within the state, as he was a strong proponent of religious tolerance and advocated for freedom of religion and expression.
