The Appropriate Sequence for the Transketolase Catalyzed Reaction Would Be

The appropriate sequence for the transketolase catalyzed reaction would be:
A.reactive enamine attack on the aldehyde group of an aldose
B.β-cleavage of Schiff base intermediate to release an aldose
C.formation of Schiff base intermediate of a new ketose
D.active site lysine forms Schiff base with keto-carbonyl group
E.Schiff base hydrated to ketose and enzyme
