Answer:
D. Christianity became divided into two distinct churches.
Step-by-step explanation:
The East-West Schism of 1054 AD was like a ten-degree earthquake in human history. Christianity was permanently divided into two parts: Western Christianity, which was the Roman Catholic Church seated in Rome and led by the pope, and Eastern Christianity, the Orthodox Church, with its center at Constantinopole and led by the patriarch of Constantinopole. It was a conflict both spiritual and of jurisdiction.
