Match List I with List II and select the correct answer using the code given below the Lists: List I (Hydroelectric Power Plant) A. Doyang B. Gomuti C. Kapili D. Ranganadi List II (State) 1. Arunachal Pradesh 2. Assam 3. Tripura 4. Nagaland Code:
- (a)A-4, B-3, C-2, D-1
- (b)A-4, B-2, C-3, D-1
- (c)A-1, B-2, C-3, D-4
- (d)A-1, B-3, C-2, D-4
Correct — A (A-4, B-3, C-2, D-1). Doyang is on the Doyang river in Wokha district, Nagaland — the only major dam in Nagaland (A-4); Gomuti (Gumti) is on the Gumti/Gomati river in Tripura, that state's principal hydro project (B-3); Kapili (Kopili) is on the Kopili river in the Dima Hasao district of Assam (C-2); and Ranganadi is on the Ranganadi (Panyor) river in Arunachal Pradesh (D-1). Each plant is named after the river it dams, and all four are North-Eastern (NEEPCO) hydro projects, so the matching is A-4, B-3, C-2, D-1.
- (b)A-4, B-2, C-3, D-1 — This swaps Gomuti and Kapili — it puts Gomuti in Assam and Kapili in Tripura. In fact Gomuti (Gumti) is in Tripura and Kapili (Kopili) is in Assam.
- (c)A-1, B-2, C-3, D-4 — Every pair is shifted — it places Doyang in Arunachal, Gomuti in Assam, Kapili in Tripura and Ranganadi in Nagaland, none of which is correct.
- (d)A-1, B-3, C-2, D-4 — This swaps Doyang and Ranganadi — Doyang is in Nagaland (not Arunachal) and Ranganadi is in Arunachal Pradesh (not Nagaland); B and C happen to be right, but A and D are wrong.
The main hydroelectric plants of India's North-East are run by NEEPCO (North Eastern Electric Power Corporation), and each is named after the river it dams. Doyang is in Nagaland, Kopili in Assam, Ranganadi in Arunachal Pradesh, and the Gumti (Dumbur) project in Tripura. Because the plant name usually matches the river, identifying the river tends to pin down the state.
The trap is that all four states are neighbouring parts of the North-East, so it is easy to shuffle them. Anchoring each plant to its river and home state — Doyang (Nagaland), Gomuti/Gumti (Tripura), Kapili/Kopili (Assam), Ranganadi (Arunachal) — sorts the list cleanly and rules out the swapped options.
- Doyang Hydro Electric Project — Doyang river, Wokha district, Nagaland; the only major dam in Nagaland.
- Kopili (Kapili) Hydro Electric Project — Kopili river and Umrong stream, Dima Hasao district, Assam.
- Ranganadi Dam — Ranganadi (Panyor) river, Arunachal Pradesh.
- Gumti (Gomuti) Project — Gumti/Gomati river, Tripura; the state's principal hydro project.
- All four are operated by NEEPCO, the North-East's central power utility.
Each NEEPCO plant is named after its river; the match is A-4, B-3, C-2, D-1.
- Shuffling the four neighbouring North-Eastern states (Nagaland, Tripura, Assam, Arunachal).
- Forgetting the shortcut that the plant name equals the river name.
Match a hydroelectric/power project to its river or state.
Which of the following pairs are correctly matched? I. Idukki — Thermal power station, II. Sabarigiri — Hydro-electric project, III. Ghatprabha — Irrigation project, IV. Ramganga — Multipurpose project.
- (a) II, III and IV
- (b) I, II, III and IV
- (c) III and IV
- (d) I and II
Answer(a) II, III and IV
Same skill — matching power/river projects to their type and location (including hydro-electric projects like Sabarigiri), the exact match-the-project reasoning this NDA item needs.
