The bond energy of a C-C (carbon-carbon) single bond is a measure of the strength of that bond, or how much energy is required to break one mole of such bonds in a gaseous substance. This value is a fundamental concept in chemistry, particularly in the study of organic molecules and reactions.

For a C-C single bond, the bond energy is typically around 83 kcal/mol (kcal per mole). This places the value closest to option C amongst the given choices.

Therefore, the correct answer is:
