The diagrams illustrate the structures of two esters, X and Y, which are produced in ripening apples. Which carboxylic acids are produced when these esters are hydrolysed by $\text{H}_2\text{SO}_4\text{(aq)}$?
- Aester X: $\text{CH}_3\text{COOH}$; ester Y: $\text{CH}_3\text{CH}_2\text{COOH}$
- Bester X: $\text{CH}_3\text{COOH}$; ester Y: $\text{CH}_3\text{CH}_2\text{CH(CH}_3)\text{COOH}$
- Cester X: $\text{CH}_3\text{CH(CH}_3)\text{CH}_2\text{COOH}$; ester Y: $\text{CH}_3\text{CH}_2\text{COOH}$
- Dester X: $\text{CH}_3\text{CH(CH}_3)\text{CH}_2\text{COOH}$; ester Y: $\text{CH}_3\text{CH}_2\text{CH(CH}_3)\text{COOH}$
