The correct answer is: dibromido bis (ethylene diamine) cobalt (III) bromide.
The correct IUPAC name of complex compound [ $\left.\mathrm{Co}\left(\mathrm{NH}_2 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{NH}_2\right)_2 \mathrm{Br}_2\right] \mathrm{Br}$ is dibromidobis (ethylene diamine) cobalt (III) bromide.
Note Here $\mathrm{H}_2 \mathrm{NCH}_2 \mathrm{CH}_2 \mathrm{NH}_2$ is ethylene diamine which is a bidentate ligand.
