An examination of a freshwater fish that died after being placed accidentally in saltwater would likely show that loss of water by osmosis from cells in vital organs resulted in cell death and organ failure. That is option C.
Osmosis is defined as the movement of water molecules through a semi permeable membrane from the region of low solute concentration to the region of high solute concentration.
The freshwater is taken as a solution that has less solute concentration while the saltwater is taken as the solution that had high solute concentration of salt.
When a freshwater fish is transferred to a saltwater, the fish will die due to cell death and organ failure which resulted from the movement of water molecules from the fish cells through the skin into the region of higher solute concentration ( saltwater).
