Answer: (B)

Verified step by step guidance

1. Understand the context: Amino acids are the building blocks of proteins, and they can link together through specific types of bonds.
2. Identify the functional groups involved: Amino acids have an amine group (\($\mathrm{NH}$₂\)) and a carboxyl group (\($\mathrm{COOH}$\)).
3. Recognize the reaction type: A dehydration reaction involves the removal of a water molecule (\($H$₂O\)) from the reactants.
4. Determine the bond formation: During a dehydration reaction between two amino acids, the carboxyl group of one amino acid reacts with the amine group of another, forming a peptide bond.
5. Visualize the process: The reaction results in the formation of a covalent bond known as a peptide bond, linking the amino acids together and releasing a water molecule.
