Solution
The correct option is A
Condensation (dehydration) reaction
An amino group reacts with the carboxyl group, forming a bond and leading to the elimination of a water molecule. This type of reaction, which involves two molecules binding to each other with eliminatiion of water is called a condensation reaction. This type of reaction is common between two amino acids, leading to the formation of a peptide bond. The general term for such reactions is condensation and the reaction can be termed peptide bond formation only when it involves two amino acids. Hydrolysis is the reverse reaction of condensation, this involves the breakdown of a large molecule into two smaller molecules by the addition of water. And oxidation is reaction involving addition of oxygen or loss of hydrogen.
