Question

Given below are two statements : Statement I : Both $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ and $\left[\mathrm{CoF}_6\right]^{3-}$ complexes are octahedral but differ in their magnetic behaviour. Statement II : $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ is diamagnetic whereas $\left[\mathrm{CoF}_6\right]^{3-}$ is paramagnetic. In the light of the above statements, choose the correct answer from the options given below :
