The correct answer is B. Salting of fish leads to diffusion of water out of the fish, causing the removal of water, making the fish drier, and thus helping in preservation.
Explanation:
Salt is commonly used as a natural preservative for all kind of food including fish, meat, and vegetables. The natural preservation salt causes can be explained as adding salt dehydrates or takes the water out of the fish or food you want to preserve and also kills or reduces most bacteria, fungi and other organisms or agents that cause decomposition to begin. In the same way, adding salt create an inhospitable environment as all of these organisms cannot survive when water is reduced. Thus, the choice that explains salting as a method for preservation is option B as this explains salt leads to diffusion of water and this helps preservation.
