(C) In the complex $Hg[Co(SCN)_4]$,the oxidation state of $Co$ is $+2$.The electronic configuration of $Co^{2+}$ is $[Ar] 3d^7$.In a tetrahedral field,$Co^{2+}$ has $3$ unpaired electrons $(n = 3)$.The spin-only magnetic moment is calculated using the formula $\mu = \sqrt{n(n + 2)} \ B.M.$$\mu = \sqrt{3(3 + 2)} = \sqrt{15} \approx 3.87 \ B.M.$
