Given below are two statements:

Statement (I): For , all three possible structures may be drawn as follows.

Statement (II): Structure III is most stable, as the orbitals having the lone pairs are axial, where the lp – bp repulsion is minimum.

In the light of the above statements, choose the most appropriate answer from the options given below:
