Option: (c)
Step-by-step explanation:
- Due to the larger size and population in Roman Empire, the Empire was divided into 2 parts.
- This can be considered as the major reason for the split in Christian church in the 11th century because the church was divided into two parts, the eastern church was called as 'Eastern orthodox church' and the other was called as 'Roman Catholic Church'.
- The bishop in the Eastern Church also 'refused to recognize' the 'authority of the pope' which caused the split.
