Read the passage given below and answer the following questions : According to Valence Bond Theory, the metal atom or ion under the influence of ligands can use its (n-1)d, ns, np or ns, np, nd orbitals for hybridisation to yield a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral, square planar and so on. These hybridised orbitals ar allowed to overlap with ligand rbitals that can donate electron pairs for bonding. Assertion (A) : In the diamagnetic octahedral complex, [Co(NH_(3))_(6)]^(3+) , the cobalt ion is in +3 oxidation state. Reason (R) : Six pairs of electrons, one from each NH_(3) molecule, occupy the six hybrid orbitals.
