Answer:
The correct answer is B.
Step-by-step explanation:
The Roman Empire (27-476) was a single entity during most of its existence, stretching across southern and central Europe from the Iberian Peninsula to modern day Turkey. However, Roman Emperor Constantine the Great converted to Christianity and established Constantinople as capital of the eastern part of the Empire. Gradually, the western and eastern parts of the empire grew apart until they were finally split in 395. The Western Roman Empire eventually fell apart because of Germanic invasions coming from Northern Europe, until Rome was finally taken over in 476. The Eastern Roman Empire, on the other hand, survived for over a millennium (395-1453), and it is today best remembered as the Byzantine Empire.
