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: \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)\right]^{3+}\) is diamagnetic whereas \(\left[\mathrm{CoF} \mathrm{F}_6\right]^{3-}\) is paramagnetic. In the light of the above statements, choose the correct answer from the options given below:

1. A  Both Statement \(I\) and Statement \(II\) are false
2. B Statement \(I\) is true but Statement \(II\) is false
3. C  Statement \(I\) is false but Statement \(II\) is true
4. D  Both Statement \(I\) and Statement \(II\) are true
