Methods of Purification of Organic Compounds

A homogeneous mixture of compounds $\mathrm{P},\mathrm{Q}$, and $\mathrm{R}$ is spotted on a thin layer chromatography ($\mathrm{TLC}$) plate. The $\mathrm{TLC}$ plate is made of acidic silica. The spotted $\mathrm{TLC}$ plate is placed in a closed jar containing diethyl ether as a mobile phase (eluent). As the eluent rises up the $\mathrm{TLC}$ plate, the compounds of the mixture separate and travel to different distances. The developed $\mathrm{TLC}$ plate is shown below.

Based on the above information, the correct statement(s) is/are
