Who among the following Mughal Princesses designed the 'bazaar' of Chandni Chowk?

Jahanara Begum

The correct answer is Option (3) → Jahanara Begum

Control over resources enabled important women of the Mughal household to commission buildings and gardens. Jahanara participated in many architectural projects of Shah Jahan’s new capital, Shahjahanabad (Delhi). Among these was an imposing double-storeyed caravanserai with a courtyard and garden. The bazaar of Chandni Chowk, the throbbing centre of Shahjahanabad, was designed by Jahanara. The term "Chandni Chowk" translates to "Moonlight Square" or "Moonlight Market," and it was named after a canal that ran through the center of the market, which would reflect the moonlight.
