Answer

Correct option: A.
Pentamminenitrocobalt $ (III)$ chloride
a
(a)In the compounds $[Co{(N{H_3})_5}N{O_2}]C{l_2}$, the oxidation state of cobalt is $ +3 $ and here $5$ $N{H_3}$ ligand, a $N{O_2}$ ligand are attached to the central atom. therefore its name is pentaamminecobalt $(III) $ chloride.
