Among the following cities, which one is at the highest altitude above mean sea level?

Bangalore (Bengaluru) sits on the Deccan Plateau at a significantly higher elevation—local surveys and studies report city elevations ranging roughly from about 720–962 m with an average near 900–920 m above mean sea level [1]. In contrast, Delhi’s average elevation is much lower, around 218 m above sea level. Jodhpur and Nagpur are also well below Bangalore in elevation (Jodhpur ≈ ~200–250 m; Nagpur ≈ ~300–350 m by standard reference values). Therefore, among the four cities listed, Bangalore has the highest altitude above mean sea level.
