Question
Consider the following statements and choose the correct
answer from the codes given below: 1. The most abundant reserves of iron ores are found in Karnataka. 2. India is the second-largest producer of iron ores in the world. 3. In India, Odisha is the largest producer of iron ores.Solution
• Statement 1: The most abundant reserves of iron ores are found in Karnataka, which is true. • Statement 2: India is the fourth largest producer of iron ores in the world, not the second. So, this statement is incorrect. • Statement 3: Odisha is indeed the largest producer of iron ores in India. This statement is true. Thus, the correct combination is 1 and 3.
