The correct answer is:
tetraammine chloridonitrito - N - cobalt(III) chloride
The oxidation number of $\mathrm{Co}$ in given complex is
$x+4 \times 0+1(-1)+1(-1)=+1$
$x=+3$
The IUPAC name of the given complex $\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}\left(\mathrm{NO}_{2}\right)\right] \mathrm{Cl}$ is tetraamminechloridonitrito-N-cobalt(III) chloride.
$\mathrm{NO}_{2}^{-}$is an ambidentate ligand name is nitrito-N means linkage is from $\mathrm{N}$ atom
$x+4 \times 0+1(-1)+1(-1)=+1$
$x=+3$
The IUPAC name of the given complex $\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}\left(\mathrm{NO}_{2}\right)\right] \mathrm{Cl}$ is tetraamminechloridonitrito-N-cobalt(III) chloride.
