Answer 1

Answer: (B), (D)

The correct options are
B Coal is obtained from decayed and buried plants inside the Earth.

D Coal is made when the decomposed organic matter faces high heat and pressure over a long period of time.


Coal is organic in nature. For millions of years, dead and decayed plant matter are getting buried inside the Earth's surface. After many millions years, many such layers of organic matter formed, one on top of the other. Because of the heat and pressure, the organic matter started experiencing changes eventually to produce coal.
