Given below are two statements:

Statement I: The number of species among BF4−,SiF4,XeF4\mathrm{BF}_{4}{ }^{-}, \mathrm{SiF}_{4}, \mathrm{XeF}_{4}BF4​−,SiF4​,XeF4​ and SF4\mathrm{SF}_{4}SF4​, that have unequal E−F\mathrm{E}-\mathrm{F}E−F bond lengths is two. Here, E is the central atom.

Statement II: Among O2−,O22−,F2\mathrm{O}_{2}^{-}, \mathrm{O}_{2}{ }^{2-}, \mathrm{F}_{2}O2−​,O2​2−,F2​ and O2+,O2−\mathrm{O}_{2}{ }^{+}, \mathrm{O}_{2}^{-}O2​+,O2−​has the highest bond order.

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