Correct Answer: The fish becomes dehydrated and dies
Solution : The correct option is The fish becomes dehydrated and dies.
When a healthy freshwater fish is exposed to saltwater (a more concentrated salty environment), it will likely dehydrate and die. This is due to osmosis, which involves the transport of water molecules through a semipermeable membrane from a low solute concentration area to a high solute concentration area.
