Answer:
The correct answer is option B. Amino acids, peptide.
Step-by-step explanation:
Dehydration synthesis is the reaction in which two or more monomers combine with one another using covalent bonds and form large polymer molecules. During this process of forming a covalent bond, water molecules are released as byproducts.
In the process of forming protein, a building a polymer of amino acids joined together to form a complex three-dimensional structure with help of peptide bonds between amino acids and remove the water molecule as the byproduct.
Thus, the correct answer is option B. Amino acids, peptide.
