Combustion of a Fat Will Release More Energy Than Combustion

Combustion of a fat will release more energy than combustion of an equal mass of carbohydrate because

A) fats contain more bonds to oxygen than carbohydrates.
B) fats contain fewer bonds to oxygen than carbohydrates.
C) the total energy of the carbon-carbon and carbon-hydrogen bonds in fats is greater than the energy content of the carbon-oxygen and oxygen-hydrogen bonds in the reaction products (carbon dioxide and water) .
D) the total energy of the carbon-carbon and carbon-hydrogen bonds in fats is greater than the energy content of the bonds in carbohydrates.
E) fats have higher molar masses than carbohydrates.
