Show answer & explanation
Correct answer: C
Concept
Statement-combination questions are solved by judging each numbered statement as independently true or false against verified facts, then selecting the option whose pair contains exactly the true statements. A single false statement inside a pair eliminates that pair, however many true statements accompany it.
Applying it to the Dawki River
Evaluating each statement on its own merits:
(i) Location in Mizoram — False. The Dawki River flows through the West Jaintia Hills district of Meghalaya, near the India–Bangladesh border at Dawki town. It is not in Mizoram.
(ii) One of the cleanest rivers — True. The river is famous for its remarkably clear, transparent water; in the dry season boats appear to float on air, and it is routinely cited among the cleanest/clearest rivers in India.
(iii) Also called Digaru River — False. The Digaru is a separate river of the Brahmaputra system in Assam and is unrelated to the Dawki.
(iv) Other name is Umngot River — True. "Umngot" is the local Khasi name for the very same river that is called "Dawki" after the town it passes; the two names refer to one river.
Result
Only statements (ii) and (iv) are correct, so the pair "(ii) and (iv)" is the answer.
Cross-check
Cross-verifying eliminates the rest: any pair containing (i) fails because the river is in Meghalaya, and any pair containing (iii) fails because Digaru is a different river. The single pair that excludes both (i) and (iii) is "(ii) and (iv)", confirming the result.
