C. roman society merged their polytheistic beliefs with Christianity
D. Christianity became the new major religion of the empire

Answer 1

The most accurate answer to how Roman society changed by the spread of Christianity is:

D. Christianity became the new major religion of the empire.

While there were various effects of Christianity's spread, including some syncretism with existing beliefs (as suggested in C) and persecution at different points, the significant change was that Christianity eventually became the dominant and officially recognized religion of the Roman Empire, especially after the Edict of Milan in 313 AD.
