Solution

The correct option is A breakage of a bond
Lyases are a category of enzymes that catalyze the breaking of bonds. This is different from hydrolysis, which involves the breaking of a bond with the help of a water molecule. An example of lyases is aldolase, which catalyzes the formation of dihydroxy acetone phosphate and glyceraldehyde 3-phosphate from fructose-1, 6-bisphosphate.
