The first National Park established in India is?

Jim Corbett National Park is the answer. It was founded in 1936 as Hailey National Park, India's first national park, and was renamed after Jim Corbett in 1957. The option is spelled "Corbelt", which is a typo for Corbett.

Core concept: national parks are legally protected areas under the Wildlife (Protection) Act, 1972, where human activity is restricted more strictly than in sanctuaries. Corbett also anchors Project Tiger, launched in 1973, so it is a useful example for Mains answers on in-situ conservation and human-wildlife conflict.

• Namdapha (Arunachal Pradesh): notified as a national park in 1983. It is notable for having all four big cats, including the snow leopard.
• Dudhwa (Uttar Pradesh): declared a national park in 1977 and lies near the Nepal border.
• Guinady (Guindy, Chennai): a small urban national park established in 1958, so it came later than Corbett and is not the first.

Trap: candidates pick Dudhwa because it is the best-known UP park, or they mix up the dates. Remember 1936 and the Hailey name.
