Answer: West Bengal
Notes: The Gangasagar Mela organizers introduced initiatives like certificates for pilgrims, e-Anushandhan for facilities access, and e-Parichay QR code identity bands. The Gangasagar Mela is an annual Hindu festival held on Sagar Island, West Bengal, at the confluence of the Ganges and the Bay of Bengal. It includes rituals like the sacred bath and Deepdan and is celebrated during Makar Sankranti, marking the Sun's transition into Capricorn. It is the second-largest religious gathering in India after the Kumbh Mela. The mela has ancient roots, with mentions in the Mahabharata's Vana Parva (1500–2000 BC).
