Among the following cities, which one lies on a longitude closest to that of Delhi ?

Bengaluru is the correct option because its longitude (approximately 77.59° E) is closest to Delhi’s longitude (77.10° E), placing the two cities almost on the same vertical line. Hyderabad is the most tempting wrong option due to its central location, but it actually lies further east at approximately 78.48° E. The core concept tested is the spatial awareness of India's north-south longitudinal alignment and the relative geographic positioning of major urban centers.
