Given below are two statements :
Statement (I) : Experimentally determined oxygen-oxygen bond lengths in the $\displaystyle \mathrm{O}_3$ are found to be same and the bond length is greater than that of a $\displaystyle \mathrm{O}=\mathrm{O}$ (double bond) but less than that of a single (O-O) bond.
Statement (II) : The strong lone pair-lone pair repulsion between oxygen atoms is solely responsible for the fact that the bond length in ozone is smaller than that of a double bond $\displaystyle (\mathrm{O}=\mathrm{O})$ but more than that of a single bond (O-O).
In the light of the above statements, choose the correct answer from the options given below :
