Given below are two statements :
Statement (I): In octahedral complexes, when $\Delta_{ o }$ < P high spin complexes are formed. When $\Delta_{ o }$ > P low spin complexes are formed.
Statement (II): In tetrahedral complexes because of $\Delta_{ t }$ <P, low spin complexes are rarely formed. In the light of the above statements, choose the most appropriate answer from the options given below:
