This question tests esterification, the condensation reaction where an alcohol and a carboxylic acid combine to form an ester and water. In acid-catalyzed esterification, the carbonyl carbon of the carboxylic acid is activated and attacked by the alcohol’s oxygen, creating a tetrahedral intermediate. Through a series of proton transfers, water is eliminated and the remaining acyl-oxygen bond rearranges to give the ester, with the acid catalyst regenerated. This process is often referred to as Fischer esterification when a strong acid drives the reaction, and the equilibrium can be shifted by using excess alcohol or removing water.

Hydration would involve adding water to a molecule, which is not the reaction here. Dehydration is a broader term for removing water, whereas the specific transformation of an alcohol and a carboxylic acid into an ester with water production is called esterification. Hydrogenation is the addition of hydrogen to multiple bonds and is unrelated.
