The correct answer B. They felt reason offered a better understanding of the world.
Explanation
During the Middle Ages, religion and faith were the main sources to explain phenomena of all kinds such as natural disasters, diseases, among others. Later, during the Enlightenment, philosophers questioned the veracity of religion as a source of explanation and, on the contrary, the reason was preferred as a means to explain everything through scientific evidence, noting that religion was not supported by reliable evidence but in speculation and facts of faith. Therefore, the correct answer is B. They felt reason offered a better understanding of the world.
