Why Is the Following Reaction Considered to Be Dehydration Synthesis $\rightarrow$

Why is the following reaction considered to be dehydration synthesis? H-NH₃C₂O-OH + H-NH₃C₂O-OH $\rightarrow$ H-NH₃C₂O- NH₃C₂O-OH + H-OH

A) Water molecules are hidden in the products H-NH₃C₂O-NH₃C₂O-OH.
B) This is the same reaction that occurs during digestion and water is required.
C) Water molecules are formed as a result of the breakdown of H-NH₃C₂O-NH₃C₂O-OH.
D) Water molecules are formed as a new, more complex end product is formed.
