Explanation:
Indian coal is known for its high ash content, which means it contains a significant amount of non-combustible minerals. However, it also has a low sulphur content, which is advantageous as high sulphur content can contribute to environmental pollution. The third statement, low ash fusion temperature, is not a characteristic of Indian coal.
