To solve this problem, we need to understand the principle behind paper chromatography.$\\$Paper chromatography is a technique used to separate mixtures of substances into their components.$\\$It involves a stationary phase and a mobile phase.$\\$• In paper chromatography, the stationary phase is the paper itself, which is made of cellulose.$\\$• The mobile phase is a solvent or mixture of solvents that moves through the paper.$\\$The separation of components in paper chromatography is primarily based on the principle of partition.$\\$This means that the components of the mixture distribute themselves between the stationary phase and the mobile phase.$\\$The distribution depends on the solubility of the components in the mobile phase and their affinity for the stationary phase.$\\$Therefore, paper chromatography is an example of partition chromatography.$\\$Let's analyze the options:$\\$• Option 1: Partition chromatography - This is correct as explained above.$\\$• Option 2: Thin layer chromatography - This involves a thin layer of adsorbent material on a glass, metal, or plastic plate,$\\$ which is different from paper chromatography.$\\$• Option 3: Column chromatography - This involves a column filled with a stationary phase, typically a solid adsorbent,$\\$ and is different from paper chromatography.$\\$• Option 4: Adsorption chromatography - This involves the separation of components based on adsorption,$\\$ which is not the primary mechanism in paper chromatography.$\\$Thus, the correct option is 1: Partition chromatography.
