Explanation
- A
4 1 3 2
Option (a) pairs Upper Bari Doab Canal with Ravi, Sirhind Canal with Sutlej, Gurgaon Canal with Sutlej, Ravi, Beas, and Indira Gandhi Canal with Yamuna. This sequence yields an incorrect matching order for the given canal and river pairs.
- B
3 2 1 4
Option (b) pairs Upper Bari Doab Canal with Sutlej, Sirhind Canal with Yamuna, Gurgaon Canal with Sutlej, Ravi, Beas, and Indira Gandhi Canal with Ravi. This incorrect arrangement fails to align the specific canal systems with their true originating rivers.
- C

Option (c) correctly matches Upper Bari Doab Canal with the Ravi River (4), Sirhind Canal with the Sutlej River (1), Gurgaon Canal with the Yamuna River (2), and the massive Indira Gandhi Canal with the Sutlej, Ravi, and Beas rivers combined (3). This established geographical alignment accurately reflects the primary water sources supplying each of these major northern Indian irrigation canal networks as examined in irrigation geography.
- D
3 1 2 4
Option (d) pairs Upper Bari Doab Canal with Sutlej, Sirhind Canal with Sutlej, Gurgaon Canal with Yamuna, and Indira Gandhi Canal with Ravi. This arrangement mixes up the primary river sources for both the Upper Bari Doab and Indira Gandhi canals.
Summary. Official key is (c) matching Upper Bari Doab Canal to Ravi, Sirhind Canal to Sutlej, Gurgaon Canal to Yamuna, and Indira Gandhi Canal to Sutlej, Ravi, and Beas. The Upper Bari Doab Canal draws its waters primarily from the Ravi River in Punjab. The Sirhind Canal is a major irrigation system taking off from the Sutlej River. The Gurgaon Canal supplies water to the arid tracts from the Yamuna River, while the Indira Gandhi Canal is fed by surplus waters of the Sutlej, Ravi, and Beas rivers through the Harike barrage. Only option (c) correctly links all four major canal networks to their exact respective river sources without any mismatch.
