Final answer:
The religious situation in the Roman Empire around A.D. 200 was characterized by syncretism, acceptance of new gods, traditional polytheism, and the cult of the emperor, making 'All of these' the best description.
Step-by-step explanation:
The religious situation in the Roman Empire circa A.D. 200 can best be described as displaying a tendency toward syncretism, willingness by the Romans to accept new gods, and sticking to polytheist traditions, including reverence for the cult of the emperor. Therefore, the correct answer is E) All of these. The era witnessed a complex religious landscape where Roman cults co-existed with traditional Roman deities, and the incorporation of gods from various parts of the empire was common. Romans did not limit themselves to their pantheon and embraced new and exotic faiths, including foreign cults and mystery religions promising spiritual salvation. The cult of the emperor also held significant sway, with deceased emperors often deified and worshiped alongside traditional gods. This period is marked by religious plurality and the later emergence of Christianity, which was initially resisted but eventually became the official religion under Emperor Constantine and later Emperor Theodosius I.
