Final answer:
The correct answer is that a dead cell exhibits membrane permeability changes. This indicates the cell's incapacity to regulate the flow of substances after death.
Step-by-step explanation:
The correct statement about a dead cell is c) It exhibits membrane permeability changes. A dead cell does not undergo active metabolism, cannot divide and reproduce, and does not maintain a stable internal environment. Once a cell dies, it often shows significant changes in membrane permeability, which means its membrane no longer selectively regulates the passage of substances in and out of the cell. This change can lead to the cell absorbing too much water or releasing its contents into the surrounding environment, which are signs of cell death.
