Answer:
A. The church combined both Greek and Roman architecture, and became a melting pot where Eastern and Western cultures came together.
Step-by-step explanation:
Hagia Sophia is an old Orthodox patriarchal basilica, built around the year 537 AD by the emperor Justinian I, it was later converted into a mosque and currently it is a museum, in the city of Istanbul, Turkey. It is considered as the epitome of Byzantine architecture. This style was in force during the Byzantine Empire (Roman Empire of the East) since the fall of the Roman Empire of the West in the 5th century. Byzantine architecture received, on a basis essentially formed by Roman architecture, strong influences from other architectural styles, especially from Greek architecture and other styles from the Middle East. These Greek and Roman styles can be seen in the Hagia Sophia, which also reflects the combination of Eastern and Western elements.
