Coordination Compounds

Given below are two statements:

Statement I: Both $[\mathrm{Co}(\mathrm{N}{\mathrm{H}}_3{)}_6{]}^{3+}$ and $[\mathrm{Co}{\mathrm{F}}_6{]}^{3-}$ complexes are octahedral but differ in their magnetic behaviour.

Statement II: $[\mathrm{Co}(\mathrm{N}{\mathrm{H}}_3{)}_6{]}^{3+}$ is diamagnetic whereas $[\mathrm{Co}{\mathrm{F}}_6{]}^{3-}$ is paramagnetic.

In the light of the above statements, choose the correct answer from the options given below:
