The correct order of C-O bond length among CO, CO₃^2-, CO₂ is,

CO₂< CO₃^2-< CO

CO < CO₃^2-< CO₂

CO₃^2- <CO₂ <CO

CO < CO₂ < CO₃^2-

Solution

CO < CO₃^2-< CO₂

The bond length is the average distance between the centres of nuclei of two bonded atoms. Centres of nuclei of two bonded atoms. A multiple bonds (double or triple bond) is always shorter than the corresponding single bond.
The C- atom is CO₃^2- is sp² hybridised as shown

The C- atom is CO₂ is sp hybridised with a bond distance of carbon -oxygen is 122 pm.
$straight O equals straight C equals straight O space left right arrow space to the power of plus straight O space identical to space straight C minus straight O to the power of minus space left right arrow space straight O to the power of minus minus straight C identical to straight O to the power of plus$
The C- atom in CO is sp hybridised with C-O bond distance is 110 pm:
So the correct order is
CO < CO₃^2-< CO₂
