B. Wild animals
C. Organisms in sea
D. Domestic animals

Answer 1

Hint: Petroleum is a fossil fuel which is formed by the degradation of many organisms. It occurs naturally through the remains of many organisms. It is a mixture of hydrocarbon (solid gas and liquid form) found in earth’s crust.

Step by step answer: petroleum is also known as crude oil (unrefined petroleum product). It is formed when marine dead organisms are buried and mixed with organic materials and other sentiments for a long period of time. It is derived from Lati word, ‘Petra’ means rock and ‘oleum’ means oil.
It is obtained from under the rocks, very dark-colored oily liquid.

Petroleum gives many products such as- transportation fuel (petrol, diesel), fuel oil for electricity generation, road oil, paraffin wax, lubricating oil etc.

Correct option is C. i.e Organisms in sea.

Dead sea organisms like animals, plants, fungus etc. when sinking to the seafloor and buried for years, they mix with organic material to produce naturally occurring oil.

Additional Information: In ancient times, oil products were valued in war weapons. Oil seeps were discovered by Spanish. American Indians reported to use this oil in medication. The utilization of this oil is a major source of energy. The possession of this oil determines the poor and rich country. For any country, its presence or non-presence determines economic growth.

Note: Petroleum oil was first discovered in 1859 by Edwin Drake in Titusville, Pennsylvania. He successfully drilled the first well through rocks and produced oil. This considered the birth of first modern oil industry
