Assertion(A)

{Ni}({CO})_4

is diamagnetic in nature.

Reason(R) Ni-atom undergoes

s p^3

hybridization.

View answer and explanation

Correct option: B

If both (A) and (R) are correct but (R) is not correct explanation for (A).

Option B (If both (A) and (R) are correct but (R) is not correct explanation for (A)) is correct because both the assertion and reason are true, but the reason does not explain why Ni(CO)4 is diamagnetic.
