Detailed Solution

Concept- A coal will be considered to be of the highest quality if it has the most carbon and the fewest impurities. Anthracite has a very high fixed carbon content (80–95%) and a very low volatile matter content.
The coal with highest carbon content is the one having high calorific value
Due to its highest carbon content and fewest impurities, anthracite is the best grade of coal, with the smoothest surface and highest calorific value.
Hence, the correct answer is option (3).
