Indian heavy water (D2O) production sites: identify the location that does not host a heavy water plant (consider the standard list used in nuclear engineering GK).

Introduction / Context:
Heavy water (chemical formula D2O) is a key material for certain reactor types such as Pressurised Heavy Water Reactors (PHWRs). India set up multiple heavy water plants to ensure a domestic supply. Many competitive exams ask you to identify which locations genuinely host these plants versus lookalike industrial towns that do not.

Given Data / Assumptions:

• We must choose the location that is not a heavy water plant site.
• Commonly cited Indian heavy water locations include Kota, Baroda (Vadodara), Talcher, Tuticorin, Thal, and Manuguru.
• Some industrial areas (e.g., Korba) are power/fertiliser hubs but not heavy water sites.

Concept / Approach:
Match each option against India’s known heavy water plant map. Kota (Rajasthan) and Baroda/Vadodara (Gujarat) are on the list. Talcher (Odisha) and Tuticorin (Tamil Nadu) are also on the list. Manuguru (Telangana) is another well-known site. Korba, despite being a major power and industrial location in Chhattisgarh, is not on the canonical list of heavy water plants. Therefore Korba is the odd one out.

Step-by-Step Solution:
List known heavy water plant locations from standard references.Cross-check each option with that list.Identify Korba as not hosting a heavy water plant.Select Korba (Chhattisgarh) as the answer.

Verification / Alternative check:
Heavy water plant lists repeatedly include Kota, Vadodara, Talcher, Tuticorin, Thal, and Manuguru; Korba does not appear among official heavy water plant locations.

Why Other Options Are Wrong:
Kota and Baroda (Vadodara): Both are established heavy water plant sites.Talcher: Recognised heavy water plant location.Tuticorin: Recognised heavy water plant location.Manuguru: Recognised heavy water plant location in Telangana.

Common Pitfalls:
Confusing nearby industrial towns and assuming any big power hub must also host a heavy water plant. Verify the exact official plant site names rather than general industrial regions.

Final Answer:
Korba (Chhattisgarh)
