Indian Rivers – Tributaries of the Indus system\nWhich of the following correctly lists the main tributaries of the Indus River system in India–Pakistan geography?

Introduction / Context:
The Indus River system in the northwest of the Indian subcontinent has several major tributaries collectively known as the five rivers of Punjab and associated streams that ultimately feed the Indus. Recognizing their names and grouping is a staple of Indian geography.

Given Data / Assumptions:

• Option (a) lists Jhelum, Chenab, and Ravi.
• Option (b) lists Beas and Sutlej.
• Together they form the classic set of five Punjab rivers that join the Indus system.

Concept / Approach:
The main tributaries in question are Jhelum, Chenab, Ravi, Beas, and Sutlej. Since options (a) and (b) split this set across two choices, the combined answer acknowledging both lists is the only complete one.

Step-by-Step Solution:
Identify the known five: Jhelum, Chenab, Ravi, Beas, Sutlej.Match them against (a) and (b): each contains a subset.Select “both (a) and (b)” to cover all major tributaries.

Verification / Alternative check:
Maps of the Indus basin show these tributaries joining westward toward Pakistan before merging into the Indus main stem.

Why Other Options Are Wrong:

• (a) or (b) alone are incomplete.
• (d) contradicts established river geography.

Common Pitfalls:
Confusing tributaries by mixing in Yamuna or Ganga basin rivers; those belong to a different system.

Final Answer:
both (a) and (b)
