Solution
The correct option is C Both vegetable and animal matter
Petroleum is also known as crude oil is a fossil fuel that was formed from the
remains of marine organisms and plant wastes (vegetable).
Millions of years ago, algae and plants lived in shallow
areas of the seas. After dying and sinking to
the sea-bottom, the organic material mixed with other sediments and was buried.
Over millions of years under high pressure and high temperature, the remains of
these organisms transformed into fossil fuels by the various chemical processes. Coal, natural gas, and petroleum are all fossil
fuels that formed under similar conditions.
Hence option D is correct.
