Answer:
A. that religious customs form an important part of culture
Explanation:
Edward Burnett Tylor (1832-1917), based on the Darwian theories of the time, defended the idea of the psychic unity of the human species in which culture developed in a progressive, linear and uniform manner. In this context, the development of cultures took place in stages, with Europe being the most advanced civilization.
Starting from this evolutionary assumption, Tylor tried to demonstrate that the emergence and development of religion would have gone through several phases as well, starting with animism, going through an intermediate phase of polytheism and ending with monotheism.
