The correct answer is option 3, which geographically pairs each National Park or Wildlife Sanctuary with the nearest town.
- Option 1, suggests Chandra Prabha is near Jaipur, which is incorrect as it`s nearest to Varanasi. Kerera being near Agra is also incorrect as it is closer to Jhansi. Jaisamand near Udaipur and Nahargarh near Jhansi are also misplacements.
- Option 2 pairs Chandra Prabha with Udaipur, which is incorrect and does similar incorrect pairings for the other places as well.
- Option 3 correctly identifies the nearest town for each National Park or Wildlife Sanctuary: Chandra Prabha to Varanasi (I-D), Kerera to Jhansi (II-B), Jaisamand to Udaipur (III-E), and Nahargarh to Jaipur (IV-A).
- Option 4, just like the first two, incorrectly pairs the sanctuaries and parks with the towns.
In conclusion, option 3 is correct as it most accurately pairs the sanctuaries and parks with their nearest towns.
