IASCODEX · Accepted Answer

Correct Option: A. Bengaluru

Strategy: Longitude is the key comparison metric here. Remember that 'closest to' means the smallest absolute difference. Delhi's longitude at 77.1°E closely matches Bengaluru's 77.6°E, with less separation than with Hyderabad, Nagpur, or Pune. Simple numeric proximity on the map gives the answer directly.

Key Info: Longitude is the angular distance of a place east or west of the Prime Meridian, measured in degrees.

Key longitudes:
- **Delhi**: 77.1025°E
- **Bengaluru**: 77.5946°E
- **Hyderabad**: 78.4867°E
- **Nagpur**: 79.0882°E
- **Pune**: 73.8567°E

Delhi and Bengaluru are both close to 77°E, meaning their geographic positions in the east-west direction are very similar, even though they differ in latitude (north-south). Hyderabad and Nagpur fall significantly further to the east, while Pune is farther west. Such comparative spatial data is crucial for Indian geography questions targeting map-based logic.
