The correct response is:
**Geography influenced the language, politics, and power centers of both the Eastern and Western Church.**
**Why this is correct:**
Geography played a crucial role in shaping the distinct characteristics of the Eastern Orthodox and Roman Catholic Churches. The geographic separation between Western Europe and Eastern Europe & Near East led to differences in language, with Latin being predominant in the West while Greek was used in the East. Additionally, the religious centers were located in different areas, with Rome as the center for the Roman Catholic Church and Constantinople, Jerusalem, Antioch, and Alexandria for the Eastern Orthodox Church.
Moreover, the political relationship to religion was influenced by geography as well, evident in the concept of Papal Supremacy in the West versus Caesaropapism in the East. These geographic influences contributed to the wider cultural and political contexts within which each church operated, ultimately leading to the East-West Schism.
