When \mathrm{AgNO}_{3} is added to KI solution, a sol of \mathrm{A g I} will be obtained.

On the surface of the sol particle, excess Iodide ions present in solution will get adsorbed to form the fixed layer. It is represented as

                    \mathrm{A g I \mid I^{\ominus}}

Hence, the correct answer is Option(1)
