B
Protein + water ____ Pepsin
C
Fat+ water ____ Lipase
D
Lactose+ water ____ Lactase
Explanation: 

Detailed explanation-1: -Pepsin Pearls Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.

Detailed explanation-2: -The specific reaction catalyzed by pepsin is the acid hydrolysis of the peptide bond. This reaction will break down proteins into smaller units to enable the digestive process.
