Easy$A$ mixture of three compounds $A, B, C$ is passed through a column of $Al_2O_3$ by using alcohol as eluant. The order in which they are eluted out of the column is $C, B, A$. Which of the following statements is true?
- A$C$ is strongly adsorbed on the adsorbent
- B$C$ is weakly adsorbed on the adsorbent
- C$A$ is weakly adsorbed on the solvent
