The places Alwaye, Koyna and Korba have
- (a) Thermal Stations
- (b) Oil Refineries
- (c) Hydro Stations
- (d) Aluminium Industries
Show the answer and explanation
Answer: (d) Aluminium Industries
The key reads all three as aluminium centres: Alwaye (Hindalco, Alupuram), Korba (BALCO), and the Koyna region (Ratnagiri/Satara).
Why the others are wrong
(a) Koyna is a hydro station, not thermal.
(b) None of them has an oil refinery.
(c) Korba is a thermal centre.
The trap
Each place is famous for something else (Koyna – dam, Korba – coal).
🔒 Aluminium: Korba (BALCO), Renukoot (Hindalco), Angul (NALCO), Jharsuguda (Vedanta), Alupuram (Kerala).
