In the context of Indian rivers, "Dihang" is another local name for which major river within India?

Introduction / Context:
Many major rivers in India are known by different local names as they flow through various regions and languages. The Brahmaputra, in particular, has several names as it travels from Tibet into India and then into Bangladesh. This question asks you to identify which river is referred to as 'Dihang' in part of its Indian course.

Given Data / Assumptions:

• The name given is 'Dihang' (or 'Dihang').
• We are dealing with Indian rivers, some of which are transboundary rivers.
• The options list major rivers: Indus, Brahmaputra, Narmada, Chenab, and Ganga.
• We need to match the local name with the correct river.

Concept / Approach:
The Brahmaputra originates in Tibet as the Tsangpo (Yarlung Tsangpo), enters India through Arunachal Pradesh, and then flows into Assam before entering Bangladesh. As it crosses into Arunachal Pradesh, it is locally known as the Dihang (or Siang). Recognising this naming pattern allows us to identify the correct river.

Step-by-Step Solution:
1. Recall that the Indus flows mainly through Ladakh and Pakistan and is not commonly called Dihang in any Indian region.2. Narmada is a peninsular river flowing westward through central India; it does not carry the name Dihang.3. Chenab is a river of the Indus system, known by names like Chandrabhaga in its early course, not Dihang.4. The Brahmaputra is known as Yarlung Tsangpo in Tibet, Dihang or Siang in Arunachal Pradesh, and Brahmaputra in Assam.5. Ganga does have multiple tributaries and local names, but Dihang is not one of its established aliases.6. Therefore, Dihang is another name for the Brahmaputra.

Verification / Alternative check:
Standard geography texts on Indian rivers clearly mention that the Brahmaputra is called Dihang (or Siang) in Arunachal Pradesh before it is joined by other tributaries and enters the plains of Assam. This consistent description across multiple sources confirms that Dihang is associated with the Brahmaputra, not with any of the other rivers listed.

Why Other Options Are Wrong:

• Indus: Known as Sindhu and by other local names, but not Dihang in Indian usage.
• Narmada: A central Indian river with a single well-known name, not commonly called by alternate names like Dihang.
• Chenab: Part of the Indus system with its own local names; Dihang is not one of them.
• Ganga: The Ganges is associated with names like Bhagirathi in its upper course, but again, not Dihang.

Common Pitfalls:
Students sometimes confuse the multiple names of major rivers, especially those with Tibetan or local tribal names. Another error is to assume that Dihang refers to a completely separate river rather than a section of a larger river. It is crucial to remember that Brahmaputra has distinct names in Tibet (Tsangpo), Arunachal Pradesh (Dihang/Siang), and Assam (Brahmaputra).

Final Answer:
In India, 'Dihang' is another name for the Brahmaputra river.
