Answer:

The correct answer is c, 40%

Explanation:

Coal is a black solid amorphous fossil fuel. It is used in the production of electricity in India. Coal is formed by a dead plant that is buried under the earth and a lot of heat and pressure worked on dead plants to form the coal.

Coal comes in three quality such as anthracite, which is the highest grade coal due to its high calorific value due to higher carbon percentage of 87% and low ash content, bituminous is the second-highest grade coal which has 77-87% carbon percentage and the last is lignite which has 70% carbon percentage with highest ash content.

India majorly produces the bituminous type of coal.

An average of 25-45% of ash content is present in the Indian coal. It is found in Jharkhand, Odisha, MP, Assam, and J&K

A higher carbon percentage in coal has the least ash content.

Hence the correct answer is C, 45%
