Which of the following orders regarding the bond length is correct?

As bond order increases bond length decreases the bond order of species are:

$$\begin{gathered} \frac{\mathrm{Number} \mathrm{of} \mathrm{bonding} \mathrm{electron} - \mathrm{Number} \mathrm{of} \mathrm{a}.\mathrm{b}. \mathrm{electron}}{2} \\ \mathrm{for} {\mathrm{O}}_2=\frac{10-6}{2}=2 \\ {\mathrm{O}}_2^{+}=\frac{10-5}{2}=2.5 \\ {\mathrm{O}}_2^{-}=\frac{10-7}{2}=1.5 \\ \text{ so bond order }{\mathrm{O}}_2^{+}>{\mathrm{O}}_2>{\mathrm{O}}_2^{-} \\ \text{and bond length are }{\mathrm{O}}_2^{-}>{\mathrm{O}}_2>{\mathrm{O}}_2^{+} \end{gathered}$$

Hence , the correct option (A).${O_2}^{-}, O_2 , {O_2}^{+}$
