Solution

The correct option is C
$C - H < C = C < C - O < C - C$

The explanation for the correct option:
Option (C): $C - H < C = C < C - O < C - C$
The average distance between the nuclei of two bound atoms in a molecule is known as bond length or bond distance.
The length of a bond is directly proportional to the size of an atom. The bond length grows as the size of the atoms increases.
Bond length of $C - H$ is shortest because of the small size of both atoms.
Bond length also depends upon the electro negativity, larger is the electronegative difference smaller is the bond length. Thus the bond length of $C - O$ is smaller than the bond length of $C - C$ .
Also the bond length of the double bond is always shorter than the single bonds because the attraction force is more between them due to the presence of more electrons i.e.bond length is inversely proportional to bond order.
Therefore, the correct order of increasing bond length is the option (C) $C - H < C = C < C - O < C - C$
