Answer:
Option: He chose Byzantium for its strategic location
Explanation:
Constantine decided to move his capital from Rome to the Greek city of Byzantium in 330 A.D. The city renamed Constantinople after Constantine. The region was chosen because of the barbarian and Persian Empire constantly attacking the empire in Rome. Constantine decided to change his capital to check the enemy advances from Danube and Persia. Its geographical location also helped him to establish capital because of its coastal city and trading network between Europe and Asia.
