Chemical Bonding · VSEPR shapes and bond order

Given below are two statements:

Statement I: The number of species among $\ce{BF4^-}$, $\ce{SiF4}$, $\ce{XeF4}$ and $\ce{SF4}$, that have unequal E–F bond lengths is two. Here, E is the central atom.

Statement II: Among $\ce{O2^-}$, $\ce{O2^{2-}}$, $\ce{F2}$ and $\ce{O2^+}$, $\ce{O2^-}$ has the highest bond order.

In the light of the above statements, choose the correct answer from the options given below
