(A) In the complex $[Co(NH_3)_6]^{3+}$,the oxidation state of $Co$ is $+3$.The electronic configuration of $Co^{3+}$ is $[Ar] 3d^6$.Since $NH_3$ is a strong field ligand,it causes pairing of electrons in the $3d$ orbitals.All $6$ electrons are paired in the $t_{2g}$ orbitals,resulting in $n = 0$ unpaired electrons.The magnetic moment $\mu = \sqrt{n(n+2)} \ BM = \sqrt{0(0+2)} = 0 \ BM$.

The magnetic moment of the complex $[Co(NH_3)_6]^{3+}$ is .....
