the least amount of carbon dioxide per unit of
energy?
(a) coal (b) oil
(c) natural gas
(d) all of these produce the same amount of
carbon dioxide.​

Answer 1

i think the answer is (c)natural gas

Answer 2

The correct answer to the given question is natural gas (option c).

• When fuel is combusted, carbon dioxide is released due to the carbon concentration in their composition.
• If the carbon level is greater, it pollutes the environment.
• The carbon content of coal and oil is extremely high.
• Because natural gas is chemically methane gas, it comprises more hydrogen content and very less carbon content in its makeup.
• As a result, when it burns, it releases the least amount of carbon dioxide per unit of energy.
