Biomolecules Intro

The equations below represent two biochemical processes, A and B. 
Equations
(A) glucose + glucose --> maltose + water

Which statement about processes A and B is correct?

• Processes A and B are examples of dehydration synthesis.
• Process A is an example of hydrolysis,  but process B is an example of dehydration synthesis.
• Process B requires enzymes, but process A does not.
• Processes A and B are examples of hydrolysis.
