The correct option is B.
The shapes of enzymes are very important because their shapes determines the kind of chemical reactions that they can catalyse. This is because the substance been catalyzed must fit into the active sites of the enzyme that is been used. In a situation where an enzyme becomes denatured, such an enzymes losses its original shape and this remove from it the capacity to catalyze chemical reactions, thus, it becomes non functional.
