Solution

$\left[\mathrm{Ni}(\mathrm{CO})_4\right]-s p^3$-hybridisation $\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}-d s p^2$-hybridisation $\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_6\right]^{2+}-s p^3 d^2$-hybridisation $\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{3-}-d^2 s p^3$-hybridisation The correct answer is A-2, B-1, C-4, D-3.

Hence, the correct answer is option: 'B'.
