Question

Which one of the following is not correctly matched ? 
Iron ore mines – State/Region

Accepted Answer

Option 1 is correctly identified as the incorrect match. Here's a detailed explanation:

1. **Dalli and Rajhara – Jharkhand**: This is not correctly matched. Dalli and Rajhara are iron ore mines located in the state of Chhattisgarh, not Jharkhand. These mines are part of the Dalli-Rajhara range, which supplies iron ore to the Bhilai Steel Plant. Therefore, the pairing of Dalli and Rajhara with Jharkhand is incorrect, making Option 1 the correct answer for the question.

2. **Baba Budan Hills – Karnataka**: This is correctly matched. The Baba Budan Hills are located in the Chikkamagaluru district of Karnataka. This region is known for its rich deposits of iron ore, making the match between Baba Budan Hills and Karnataka accurate.

3. **Karimnagar – Telangana**: This is correctly matched. Karimnagar is a district in the state of Telangana, and it is known for its mineral resources, including iron ore. Therefore, the association of Karimnagar with Telangana is correct.

4. **Noamundi and Gua – Jharkhand**: This is correctly matched. Noamundi and Gua are well-known iron ore mining areas located in the state of Jharkhand. These mines are significant contributors to the iron ore production in the region, making the match between Noamundi and Gua with Jharkhand accurate.

In conclusion, Option 1 is the correct answer because it incorrectly matches Dalli and Rajhara with Jharkhand, whereas they are actually located in Chhattisgarh. The other options are correctly matched with their respective states or regions.
