"They built The Hagia Sophia" was not a major advancement made by Muslims

Option 1

Explanation:

At present, Hagia Sophia is a museum in Istanbul since 1935 and listed as UNESCO World Heritage Site, but earlier it was “Ottoman imperial mosque” and earliest “Christian patriarchal cathedral”. Byzantine emperor/Eastern Roman emperor “Justinian I”  ordered for its construction from 532-537, designed by Isidore of Miletus & Anthemius of Tralles and remarked as paragon of “Byzantine architecture”.

“Muhammad ibn Musa al-Khwarizmi” called as father of algebra. Earliest public hospital was established in Baghdad during 805 by “Harun Al-Rashid”. Islamic astronomy made remarkable amendments in Star charts of ancient Greeks where Altair, Aldebaran & Denab are highlighted star’s name while astronomical terms like nadir, alidade etc are Islamic words.
