Right choice is (a) True
The best explanation: Enzyme use in detergent industry is cost effective and safe due to the development of a dust free granulate with an inner core containing enzyme, inorganic salts and sugars as preservative bound with carboxymethyl cellulose fibers or similar protective colloid. This is then coated with inert waxy material made of paraffin oil/ polyethylene glycol with various hydrophobic binders, which later disperse in wash. This prevents dust formation and protects enzyme against damage during storage. Hence the statement is true.
