Solution

The correct option is C $C - C$
Bond energy is the average value of the gas-phase bond dissociation energies for all bonds of the same type within same chemical species.

The order of bond energies are: $C - C > N - N > O - O > F - F$ because there are less electrostatic repulsions when the atoms do not have lone pair.
