- Rudraprayag
- Karnaprayag
- Nandaprayag
- Vishnuprayag
The correct sequence is Vishnuprayag (with the Dhauliganga) → Nandaprayag (Nandakini) → Karnaprayag (Pindar) → Rudraprayag (Mandakini), after which the Alaknanda meets the Bhagirathi at Devprayag to form the Ganga. Options (a), (b) and (c) each swap a pair of neighbouring confluences — the mnemonic “Vishnu-Nanda-Karna-Rudra” keeps the order straight.
The Son is a major right-bank (peninsular) tributary of the Ganga, joining it near Maner, west of Patna. The Yamuna is a right-bank tributary, not a left-bank one, while the Ghaghara, Gandak, Kosi and Ramganga are left-bank tributaries from the Himalayas. The Chambal joins the Yamuna near Etawah, not the Ganga.
- The Narmada and the Tapi flow westward through rift valleys and form estuaries instead of deltas.
- The Godavari is the longest river of peninsular India and is also called the Dakshin Ganga.
- The Tapi is the longest west-flowing river of peninsular India.
- The Luni, originating in the Aravallis near Ajmer, drains into the Bay of Bengal.
Statement 1 is correct — both rivers run through rift valleys (graben) and empty into the Arabian Sea through estuaries. Statement 2 is correct — the Godavari (about 1,465 km) is the longest peninsular river. Statement 3 is incorrect — the Narmada (about 1,312 km) is the longest west-flowing river, and the Tapi is much shorter. Statement 4 is incorrect — the Luni is an inland-drainage river of Rajasthan that ends in the Rann of Kachchh.
- Assertion (A): The rivers of the Peninsular plateau are mostly seasonal in nature.
- Reason (R): Himalayan rivers are perennial because they are fed by glacier melt as well as monsoon rainfall.
A is correct — peninsular rivers depend almost entirely on rainfall, so their flow varies sharply between seasons. R is also correct — Himalayan rivers such as the Ganga, Indus and Brahmaputra receive snow- and glacier-melt in addition to rainfall. However, R describes a different group of rivers: a peninsular river is seasonal because of its own rain-fed catchment, not because Himalayan rivers are perennial.
- Statement 1: The Ken and the Betwa are both right-bank tributaries of the Yamuna.
- Statement 2: The project falls under the Himalayan Rivers Development component of the National Perspective Plan.
Statement 1 is correct — the Ken joins the Yamuna near Banda and the Betwa near Hamirpur, both in Uttar Pradesh, so the project links two rivers of the Bundelkhand region. Statement 2 is incorrect — it belongs to the Peninsular Rivers Development component of the National Perspective Plan (1980), not the Himalayan one. The Daudhan dam on the Ken lies within Panna Tiger Reserve, the project’s main ecological concern, and the foundation stone was laid in December 2024.
