Concept:Salting removes the most water from fish through osmosis, which dries the fish tissue.
Explanation:When salt is applied to fish, it creates a concentration difference that pulls moisture out of the fish cells.
This process is called osmosis.
The heavy salt draws water from deep inside the fish, causing maximum dehydration.
Freezing and smoking preserve fish by lowering temperature or drying with smoke, but they do not cause as much direct water loss as salting.
Because salting directly removes the largest amount of water, it is the correct answer.
Answer:C. salting
