In the reaction below, two glucose monomers combine to form the dimer maltose. Which of the following best explains the process of this reaction?

• To form a covalent bond, the monomers underwent a hydrolysis reaction.

• An ionic bond forms through dehydration synthesis, which combines the two glucose monomers and forms the maltose dimer.

• Water is added to the reaction to promote the formation of a covalent bond between the glucose monomers.

• A covalent bond forms through dehydration synthesis, which results in the formation of maltose and water.
