Final answer:
Dehydration, freezing, and preserving in salt or sugar are all processes used to remove moisture from foods.
the correct answer is 4) All of the above
Step-by-step explanation:
The processes used to remove moisture from foods include dehydration, freezing, and preserving in salt or sugar. Dehydration works by drying out the food, either through evaporation in the sun or through freeze-drying in a vacuum. Freezing also removes moisture from the food, as the water in the food turns into ice. Preserving in salt or sugar reduces the amount of available water in microbial cells, preventing their growth.
