Which one of the following is not correctly matched ?

The correct answer is B. Hangul, the Kashmir stag (Cervus hanglu hanglu), is found in Dachigam National Park near Srinagar, not in Periyar. Periyar in Kerala is known as a tiger reserve and elephant habitat, with Nilgiri tahr and Indian bison also present.

Checking the other pairs:

• Rajaji National Park (Uttarakhand) is a recognised elephant habitat and corridor, so this pair is correct.
• Manas National Park (Assam) is a Project Tiger and Project Elephant site with a large elephant population, so this is correct.
• Dudhwa National Park (Uttar Pradesh) is a Terai tiger reserve, so this is correct.

The core concept is species-habitat association within protected areas, tied to Project Tiger, Project Elephant and Hangul conservation. For Mains, this links to human-wildlife conflict and the role of wildlife corridors. Hangul's range has shrunk to Dachigam and adjoining areas, so its status is now more restricted than the 2014 framing suggests.

Trap: Aspirants remember Periyar as an elephant reserve and assume it belongs on every large-mammal list, or they place Hangul in the wrong Kashmir park.
