Solution

The correct option is C III > IV > I > II
The decrease in CC σ bond length as C hybridization changes from sp3 to sp2 to sp reflects the decrease in the bond length. The shortening of all these bonds is a consequence of the adjacent double and triple bonds. The the carbon-carbon single bond of the alkyne is shorter than alkene and those of alkane. The order of bond length is II<I<IV<III
