Show answer & explanation
Correct answer: C
Answer: The Ganga river stretch between Allahabad and Haldia is the longest waterway in India.
Key fact: This stretch is designated National Waterway 1 and runs for about 1,620 km, making it the longest inland waterway in India.
Why the Brahmaputra stretch is not correct: The Brahmaputra stretch between Sadiya and Dhubri is National Waterway 2 and is significantly shorter than the Ganga's National Waterway 1.
Why the West-Coast canal is not correct: West-Coast canals serve regional/coastal navigation and have much shorter total navigable length than the Ganga stretch.
Why the Narmada-related choice is not correct: Narmada sections or East–West canal areas are not the longest designated inland waterway in the country and are shorter than National Waterway 1.
Takeaway: Choose the Ganga river between Allahabad and Haldia because it corresponds to National Waterway 1, the longest inland navigation route in India.
