Correct Answer: Option B

Explanation

The chemical reaction illustrated in the question above is an esterification reaction. Esterification reaction is the reaction between an alkanol (alcohol) and an alkanoic acid (carboxylic acid) in the presence of an acid catalyst forms an ester (alkanoate) and water. To produce alkanoates (esters) from alkanols and alkanoic acids, you need to perform esterification, which requires a concentrated acid catalyst (like H\(_2\)SO\(_4\)) and heat.
