Correct answer choice is :
D) Humanism promoted secularism through the study of philosophy, literature, and science.
Step-by-step explanation:
Humanism is a liberal viewpoint of life that, without theism or other spiritual faiths, declares our strength and accountability to direct moral lives of individual achievement that seek to the greater good. Secularism is a faith system that denies religion, or the faith that religion should not be part of the activities of the state or part of public education. The laws of separation of church and state and of having religion out of the public school system are a part of secularism.
