The correct answer is A) 1 and 2 only. Statements 1 and 2 accurately describe characteristics of Indian coal, while statement 3 is incorrect.

Indian coal is known for its high ash content and relatively low sulphur content compared to coal found in many other parts of the world. The ash fusion temperature of Indian coal is generally high, which can lead to operational issues like slagging in boilers if not properly managed.

High ash content reduces the energy output per unit weight and increases transportation costs and environmental challenges related to ash disposal. Low sulphur content is an advantage from an environmental perspective as it results in lower sulphur dioxide emissions. The high ash fusion temperature means that the ash melts at a higher temperature, but if furnace temperatures exceed this point, it can form slag, which sticks to boiler tubes.
