मुंबईचा एक भाग एस्प्लनेड याचे नंतर ______ असे नाव ठेवण्यात आले.

The correct answer is Option C (Azad Maidan).

Key Points:
• Historical Legacy of Azad Maidan (Mumbai):
• During the British colonial era, the vast open space stretching south of the ramparts of Bombay Fort was maintained as a clear firing range and open military ground, known as the 'Esplanade'.
• After the demolition of the Fort walls in the 1860s, the Esplanade was divided into different public spaces (including Cross Maidan, Oval Maidan, and the main Esplanade Maidan).
• The central northern part of the Esplanade Maidan (opposite CSMT/BMC headquarters) became the historic epicenter of massive freedom rallies, protests, political speeches by Mahatma Gandhi, Jawaharlal Nehru, and nationalist leaders.
• After Indian independence, this iconic Esplanade Maidan was officially christened as 'Azad Maidan'. (Note: Gowalia Tank was renamed August Kranti Maidan).
• Key Takeaway: The historic British colonial 'Esplanade Maidan' in Mumbai was later renamed as 'Azad Maidan'.
