‘Dooth-Ganga’ river is located in

The correct answer is A) Jammu and Kashmir. The Dudhganga (spelled Doodhganga or Dudhganga in most sources) is a right-bank tributary of the Jhelum, rising in the mountains north of the Kashmir valley and flowing into the Jhelum near Srinagar. The Dudhganga Wildlife Sanctuary, close to Srinagar, is a well-known protected area on its course.

• B) Himachal Pradesh: Himachal's major rivers are the Beas, Ravi, Sutlej, Chenab and Yamuna's upper tributaries. No river of this name is associated with the state.
• C) Uttarakhand: The state has the Alaknanda, Bhagirathi, Mandakini and Kali, and the Dhauliganga, which is often confused with Dudhganga. Dhauliganga is not the same river.
• D) West Bengal: The state's rivers are the Ganga, Hooghly, Teesta, Mahananda and Damodar. A Dudhganga is not a feature of West Bengal's geography.

The core concept is the Jhelum basin and the Kashmir drainage system, which also links to Mains questions on Himalayan hydrology and the Indus Waters framework.

Trap: Candidates confuse Dudhganga with Dhauliganga or with a Dudhganga in Maharashtra (a tributary near Kolhapur). Anchor the Kashmir one to the Jhelum.
