It's Wrong!
The correct answer is "Constantinople". Istanbul was previously called Constantinople, which was the city's name during the Byzantine Empire and later the Ottoman Empire. The name Constantinople was given to the city in the 4th century AD in honor of the Roman Emperor Constantine the Great. The name was officially changed to Istanbul in 1930, following the establishment of the modern Republic of Turkey.
