Answer:
The correct answer is - end product.
Step-by-step explanation:
A dehydration reaction is a chemical reaction that occurs between two compounds in which water is one of the end products.
When two monomers may react to one another and an H or hydrogen atom of one monomer binds to OH or hydroxyl group of another monomer to make a dimer. In this reaction the end products that form are water and a dimer, it is an example of the dehydration reaction.
Thus, the correct answer is - end product.
