Characteristics of Indian Coal

Indian coal is characterised by high ash content (statement 1 is correct) and low ash fusion temperature (statement 3 is correct), which are significant drawbacks affecting its quality. However, Indian coal typically has moderate to high sulphur content, not low sulphur content (statement 2 is incorrect). The high ash content requires more processing and increases handling costs, while low ash fusion temperature causes slagging problems in furnaces. These characteristics distinguish Indian coal from coals found in developed countries. > Indian coal = High ash + Low ash fusion temp (both problematic); not low sulphur. Answer: (c).
