Since the fish is constantly taking in water at its gills, it needs to regulate the amount of salt in its body. It does this by producing dilute urine to remove excess water and actively transporting salt ions into its body at the gills. This allows the fish to maintain a proper balance of salt and water in its cells. Drinking seawater (as in choices B and C) would actually make the problem worse, since the fish would take in even more salt and have to work even harder to get rid of it.
