The correct answer is A) Bellary-Hospet region.
The Bellary-Hospet region is a major iron ore producing region in India. The region is home to several iron and steel plants, including the National Mineral Development Corporation’s (NMDC) Kudremukh Iron Ore Company Limited (KIOCL) and the Jindal Steel and Power Limited (JSPL) plant.
The Bellary-Hospet region is also home to several other industries, including mining, power generation, and manufacturing. The region is well-connected to other parts of India by road, rail, and air.
The other options are incorrect because:
- Option B, Coastal Karnataka, is not a major iron ore producing region.
- Option C, Malnad region, is a hilly region in Karnataka that is not suitable for iron ore mining.
- Option D, Southern Karnataka, is a large region that includes several different types of terrain, including coastal areas, hills, and plains. The iron and steel industry is not concentrated in any one part of Southern Karnataka.
