Q99
Question
Consider the following information: Waterfall — Region — River: 1. Dhuandhar — Malwa — Narmada; 2. Hundru — Chota Nagpur — Subarnarekha; 3. Gersoppa — Western Ghats — Netravati. How many of the above rows is the given information correctly matched?
AnswerOption B
Explanation
The correct answer is option (B). Dhuandhar Falls is on the Narmada but is associated with the Marble Rocks/Jabalpur region rather than Malwa; Hundru Falls is on the Subarnarekha in the Chota Nagpur Plateau; Gersoppa (Jog) Falls is on the Sharavathi, not the Netravati. Thus only one row is correctly matched. The key to this question is to distinguish the exact constitutional provision, factual association, scientific principle, or current-affairs detail being tested from statements that are partly true but incomplete or incorrectly framed. UPSC often makes the distractors plausible by changing one institutional role, date, classification, geographic association, or causal relationship. Option A — “Only one” is incorrect. It does not match the established fact or contains the incorrect combination, institution, relationship, classification, or proposition identified in the explanation above. Choosing it would therefore introduce a factual error or omit a necessary element. Option B — “Only two” is correct. It matches the established fact described above and gives the complete combination or identification required by the question. Option C — “All three” is incorrect. It does not match the established fact or contains the incorrect combination, institution, relationship, classification, or proposition identified in the explanation above. Choosing it would therefore introduce a factual error or omit a necessary element. Option D — “None” is incorrect. It does not match the established fact or contains the incorrect combination, institution, relationship, classification, or proposition identified in the explanation above. Choosing it would therefore introduce a factual error or omit a necessary element. For examination purposes, the safest approach is to verify each statement independently before looking at the answer-code combination. This is particularly important in statement-based questions, because one false clause makes an entire combination wrong. In factual questions, compare the defining characteristic asked in the stem with each alternative rather than relying on superficial familiarity. The answer recorded here follows the verified Set C key used for this database.
