Solution

The correct option is A Pure substance
Paper chromatography is a method for separating dissolved substances from one another. It is often used when the dissolved substances are coloured, such as inks, food colourings and plant dyes. A pure substance will only produce one spot on the chromatogram during paper chromatography.
