Answer
The reaction involves butanoic acid (C₄H₈O₂) and pentanol (C₅H₁₂O). Butanoic acid is a carboxylic acid and pentanol is an alcohol, making it a typical esterification reaction.

Answer
When butanoic acid reacts with pentanol in the presence of an acid catalyst, an ester is formed. The general reaction for esterification can be expressed as:
RCOOH+R′OH→RCOOR′+H2O
In this case, the ester formed will be pentyl butanoate, which is represented by option (B).
