Answer:
A) the Roman Empire
Step-by-step explanation:
The Byzantine Empire was the remaining surviving part of the former Roman Empire, after it felt in the 5th century CE
Constantine decided to shift the capital from Rome to Constatinople, in which also Christianity became the official religion of the Byzantine Empire.
He also used Latin rather than Greek as the official language- this meant that he preserved both Greek and Roman legacy alive for almost a century after the Roman Empire was unable to withstand westwards.
Of course for many the Byzantine Empire is the continuation of the Romans in East, but Byzantine also embraced Hellenistic elements which resulted into very unique forms of art, architecture and religion.
Sine significant differences emerged:
For Romans the main religion was polytheistic where they worshiped the various renamed Greek gods. Emperor Constantine I’s rule was when Christianity was the main religion of the empire.
The Roman Empire, before its division, covered a larger geographical area that the Byzantine Empire ever did. The image shows both West and East Roman Empire and in purple highlights Byzantine Empire
