Atomic number of Mn, Fe, Co and Ni are 25, 26, 27 and 28 respectively. Which of the following outer orbital octahedral complexes have same number of unpaired electrons?

${\left[{\mathrm{MnCl}}_6\right]}^{3-}$and ${\left[{\mathrm{CoF}}_6\right]}^{3-}$ outerorbital octahedral complexes have same number of unpaired electrons. ${\left[{\mathrm{MnCl}}_6\right]}^{3-}$ is an outer orbital complex or a high spin complex with a paramagnetic magnetic characteristic (the number of unpaired electrons is 4). ${\left[{\mathrm{CoF}}_6\right]}^{3-}$ As a weak field ligand, the fluoride ion is unable to pair the third-order electrons. Hence, options A and C are correct.
