Answer 2

Coal is obtained from sedimentary rocks.

Option: A

Explanation:

• Sedimentary rocks are the ones formed from layers of deposition over millions of years. They are also called striated rocks.  

• ‘Sedimentary rocks’ are usually formed from biotic sources.

• Millions of years ago the dead remains of plants got buried deep beneath the earth.  

• With force and pressure these remains slowly got compressed and with the years solidified to form ‘sedimentary rocks’ called fossil rocks.  

• Coal is such a kind of fossil rock that has been formed in long layers below the earth and has to be mined out.
