Solution

The correct option is C $1 : 2$ electrolyte
$0.2 m o l$ of $A g C l$ are obtained when $0.1 m o l C o C l_{3} (N H_{3})_{5}$ is treated with excess of $A g N O_{3}$ which shows that one molecule of the complex gives two $C l^{-}$ ions in solution.
Thus, the formula of the complex is $[C o (N H_{3})_{5} C l] C l_{2}$ i.e. $1 : 2$ electrolyte.

Hence, Option "B" is the correct answer.
