Which one among the following cities is called the ‘zero-mile centre’ of India?

Nagpur is widely recognized as the ‘zero-mile centre’ of India [1]. The Zero Mile Stone is a historical monument located in the city, which was established by the British during the Great Trigonometrical Survey of India. The British considered Nagpur to be the geographical center-point of colonial India and used this specific marker as a reference to measure the distances of all other major cities across the subcontinent. The monument consists of a sandstone pillar and statues of four horses, situated at an elevation of approximately 1020 feet above sea level. While modern calculations suggest the exact geographical center may lie elsewhere, Nagpur remains the historic and symbolic 'Zero Mile' marker of the country. Due to its central location, the British even considered making Nagpur the second capital of India.
