Answer:
Enlightenment thinkers believed in **B) Democracy.**
Step-by-step explanation:
The Enlightenment was an intellectual movement that took place in Europe during the 17th and 18th centuries. Enlightenment thinkers advocated for various principles and ideas, including reason, individualism, liberty, and the belief in the power of people to govern themselves through democratic means. Prominent Enlightenment philosophers like John Locke, Jean-Jacques Rousseau, and Montesquieu played a significant role in shaping the foundations of modern democratic thought. They argued for the importance of representative government, the protection of individual rights, and the idea that political authority should be based on the consent of the governed. Democracy, with its emphasis on popular sovereignty and the rule of law, was a central theme in Enlightenment philosophy.
