Complete answer:
Millions of years ago when aquatic flora and fauna died in shallow seas , they sank to the bottom of the sea and after sinking the matter got mixed with the sediments and was buried deep inside the seafloor. After being exposed to Earth;s pressure and heat, for millions of years, the buried dead and decaying matter converted into something we know as fossil fuel in today’s time. Under similar conditions different types of fossil fuels were formed, these included natural gas, coal and petroleum.

Petroleum is a type of fossil fuel which is found deep buried in reservoirs, a place where ancient seas used to be located millions of years ago. Reservoirs of petroleum are usually found under the ocean or land floor. Out of this petroleum, crude oil gets drilled in order to be extracted. Gasoline, a product that has a lot of usage, gets made because of petroleum. A lot of different types of products are also made by using petroleum, these include jet fuel, waxes, lubricants, petrochemical feedstocks etc. Coal is a type of sedimentary rock which is brownish-black or balck in colour. Coal is mostly made of hydrocarbons and carbons and due to this energy is produced when it is burnt. This energy producing quality of coal is used to generate electricity, thermal power to be exact.

Hence, the correct answer is option (B).

Note:Venezuela in South America has the largest reserves of petroleum in the world while the United States of America has the largest reserves of petroleum in the world.
