Answer:
Option (B)
Explanation:
Coal is a fossil fuel that is formed from the burial of ancient plants and trees, that are deposited millions of years ago. It can not be regenerated again and again. These floras were deposited earlier in a tropical type of climate because the tropical regions receive a good amount of sunlight and rainfall that favours the growth of abundant plants and trees.
Coal is usually dark black to brownish in colour and is a combustible rock. It is primarily comprised of carbon. In addition to this, some amount of other elements are present such as hydrogen, oxygen, nitrogen, and sulfur. These are sedimentary rocks and often produces carbon when burnt.
Thus, the correct answer is option (B).
