(A) The reaction involves the alkaline hydrolysis of an ester using $KOH$ in $H_2O/\Delta$. The reactant is a tert-butyl ester. Alkaline hydrolysis of an ester (saponification) yields a carboxylate salt and an alcohol. $1$. The ester group $(CH_3)_3CO-CO-CH_2-CH_2-CH(OH)-Ar$ undergoes hydrolysis to produce tert-butanol $(CH_3)_3COH$ and the corresponding carboxylic acid,which immediately reacts with $KOH$ to form the carboxylate salt $HOOC-CH_2-CH_2-CH(OH)-Ar$ (which becomes the carboxylate anion). $2$. The ether groups ($-OCH_3$ and $-OCH_2CH_2CH_3$) attached to the aromatic ring are stable under these basic conditions and do not react. $3$. The hydroxyl group $(-OH)$ on the aliphatic chain is also stable under these conditions. Thus,the products are tert-butanol and the carboxylate salt of the carboxylic acid. Total number of products = $2$.

Total number of products obtained in the above reaction is:
