Enzymes are highly substrate-specific, and their names often reflect the substrate they act upon. Caseinase is an enzyme that specifically digests casein, a milk protein, so pairing Caseinase with Casein is the correct match. Gelatinase would act on gelatin, not casein, making that pairing incorrect for this question. Tributyrase targets tributyrin (a fat), not gelatin, so that one doesn’t fit either. Protease is a general protein-digesting enzyme, but starch is a carbohydrate and requires a starch-degrading enzyme like amylase, not a protease. So the most accurate pairing is Caseinase with Casein.
