Which one of the following peaks is NOT located in India?

Kamet (7,756 m) lies in Chamoli district of Uttarakhand, so it is clearly in India. Gurla Mandhata (7,728 m) is in Ngari prefecture of Tibet, China, near Mansarovar, even though Indian pilgrims pass close to it on the Kailash-Mansarovar Yatra. That makes it the keyed answer.

• B) Namcha Barwa (7,782 m): also lies in Tibet, north of the McMahon Line, at the Great Bend of the Yarlung Tsangpo. It is not in India either, so this question is less clean than it looks.
• C) Kamet: an Indian peak, and the second-highest in Uttarakhand after Nanda Devi.
• D) Nanga Parbat (8,126 m): lies in Gilgit-Baltistan, administered by Pakistan. India claims it as part of Jammu and Kashmir, so it is outside Indian administration, not in India in practice.

The concept is the geography of the Himalayan ranges and the political division of Himalayan territory among India, China and Pakistan. This connects to the Brahmaputra and the Indus water questions in Mains GS-1 and GS-2.

Trap: assuming only Nanga Parbat is foreign-held, or treating Gurla Mandhata as Indian because of the Mansarovar yatra route.
