Answer 2

‘Petroleum’ is formed from animals and plants which got buried under the ocean millions of years ago.

Option: A  

Explanation:

• Petroleum is a biotic mineral which means it has been formed from the dead remains of plants and animals.  

• Millions of years ago plants and animals had been buried on the ocean floor.  

• With pressure from above and lateral compression these plant and animal remains have been so compressed that they have turned into fossils and with time the fossils have liquefied to form an oily mineral.  

• This mineral is an excellent fuel and hence is called a fossil fuel. Currently it is called petroleum.
