Explanation
Immanuel Kant 1724 - 1804) was a Prussian philosopher of the Enlightenment, noted for being one of the most influential thinkers of modern Europe and universal philosophy. One of his most popular publications is "Critique of Pure Reason", in which he wrote about the structure of reason itself. Also, he made important advances in science, law, morals, religion, and history, having achieved, in this way, he managed to relate empiricism and rationalism by proposing that although all our knowledge begins with experience, no everything arises from it, because reason plays an important role in this process. One of Kant's most important approaches was that of the "immaturity" (in opposite to Enlightenment) he used to refer to individuals who did not use their own reasoning and rely on other individuals. In addition, Kant affirmed it was through Enlightenment or self-reasonin that individuals could get out of that immaturity. So, the correct answer is B. Think for themselves.
