An ester that smells like banana has the formula $\text{CH}_3\text{CO}_2\text{CH}_2\text{CH(CH}_3)\text{CH}_2\text{CH}_3$. Which pair of reactants, under suitable conditions, would form this ester?
- A$\text{CH}_3\text{CH}_2\text{CH(CH}_3)\text{CH}_2\text{CO}_2\text{H} + \text{CH}_3\text{OH}$
- B$\text{CH}_3\text{CH}_2\text{CH(CH}_3)\text{CO}_2\text{H} + \text{CH}_3\text{CH}_2\text{OH}$
- C$\text{CH}_3\text{CO}_2\text{H} + \text{CH}_3\text{CH}_2\text{CH(CH}_3)\text{CH}_2\text{OH}$
- D$\text{CH}_3\text{CO}_2\text{H} + \text{CH}_3\text{CH(CH}_3)\text{CH}_2\text{OH}$
