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) : The paramagnetic octahedral complex, `[CoF_(6)]^(3-)` uses outer orbital (4d) in hybridisation `(sp^(3)d^(2))`.
Reason (R) : It is a high spin complex.

Options

A. Assertion and reason both are correct statements and reason is correct explanation for assertion.
B. Assertion and reason both are correct statements and reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement
D. Assertion is wrong statements but reason is correct statement.

Answer

C

Explanation

The paramagnetic octahedral complex, `[CoF_(6)]^(3-)` uses outer orbital (4d) in hybridisation `(sp^(3)d^(2))`. It is a low spin complex.
