(C) In Thin Layer Chromatography $(TLC)$,the separated components are often invisible to the naked eye. To visualize them,several techniques are used: $1$. $I_{2}$ (Solid) chambers: Iodine vapors adsorb onto the components,making them visible. $2$. $U.V.$ Light: Many organic compounds fluoresce under $U.V.$ light. $3$. Spraying of an appropriate reagent: Chemical reagents react with the components to produce colored spots. However,adding a visualization agent directly to the mobile phase is not a standard technique for spotting components on a $TLC$ plate,as it would interfere with the separation process itself.

Which one of the following techniques is not used to spot components of a mixture separated on a thin layer chromatographic plate?
