We can expect to find carbon in all living organisms and in all organiccompounds. So the correct options are A and C.
Carbon is an element found on the earth. It is an extremely abundant element with unique properties. Carbon is present in the environment in pure or almost pure forms.
Diamonds and graphite are some of the pure forms of carbon. Carbon also forms compounds with other elements for the formation of molecules.
These carbon-based molecules are the basic building blocks of all living organisms including humans, animals, plants microorganisms etc.
These also present many components of the environment. They are called organic molecules. Greenhousegases like carbon dioxide and methane are examples of carbon-based molecules.
They are also present in high percentages of fossilfuels. They are mainly made up of hydrocarbons which are molecules composed of hydrogen and carbon.
Therefore the correct options are A and C.
