Project Tiger is a major conservation program launched in India in 1973 to protect the Bengal tiger. Project Tiger Reserves are designated areas critical for tiger conservation. A) Dudhwa National Park in Uttar Pradesh is a recognized Tiger Reserve. B) Chilika Lake in Odisha is a brackish water lagoon and a Ramsar Site known for its rich biodiversity, especially birds, but it is NOT a Project Tiger Reserve. C) Kanha National Park in Madhya Pradesh is a well-known and important Tiger Reserve. D) Manas National Park in Assam is a Tiger Reserve and a UNESCO World Heritage site. Therefore, Chilika is not a Project Tiger Reserve.
