Solution

The correct option is B 3 and 6
The primary valency of $C o$ is 3 and the secondary valency of $C o$ is 6.
The primary valency represents the number of ions in the ionization sphere and the secondary valency represents the number of ligands.
In this example, one chlorine atom serves dual role.
