The size of $SP$ orbital is shortest and that of $SP^3$ is longest $(SP^3 > SP^2 > SP)$.
The hybridisation involved in ethane is $SP^3, $ ethene is $SP^2$ and ethyne is $SP$
The $C-C $ bond length is longest $(1.54 A^{\circ})$, $C=C$ bond length is $1.34 A^{\circ}$ .
In benzene $C-C$ bond length is $1.39 A^{\circ}$.
Hence a is the correct answer.
