The correct answer is adding ninhydrin to developing solvent.

Ninhydrinis used to detect (color) amino-acids, since amino acids are colourless compounds. So, after development, the TLC plate is sprayed with ninhydrin reagent and dried in an oven, at 105°C for about 5 minutes. It reacts with α- amino acids that results in purple coloured spots.
