(D) In column chromatography,the compound that elutes first has a weaker interaction with the stationary phase and a higher $R_f$ value. Conversely,the compound that elutes later has a stronger interaction (adsorption) with the stationary phase and a lower $R_f$ value. Since '$A$' eluted first,'$B$' must have eluted later. Therefore,'$B$' has a lower $R_f$ value and stronger adsorption to the stationary phase. $R_f = \frac{	ext{distance covered by substance}}{	ext{distance covered by solvent}}$

Using column chromatography,a mixture of two compounds '$A$' and '$B$' was separated. '$A$' eluted first,this indicates '$B$' has
