The CORRECT ANSWER IS a)
a) loss of the Balkan provinces to the Slavs
Step-by-step explanation:
The Byzantine Empire derives its name from the set of the Roman Empire that scaled through in the course of the Late Antiquity and the Middle Ages.
It is also referred to as the Eastern Roman Empire.
This empire is well known to have Constantinople as the capital city, and it was growing and existing before its fall to the Ottoman Turks in 1453.
