Long:
First of all, lets eliminate the easy ones. Just think if a animal in the artic moved to the desert... Something would happen; so its not D. And I don't think it would be A either. So we are left with B and C... Well, water is absorbed by salt. Cells = water. Saltwater fish have adapted to this by becoming more hypotonic, which allows more water to flow through their body faster and they have also adapted to carry more water in their cells. Freshwater happen to be not, so the salt will absorb their water in the cells and eventually ending the fish's life.
