The correct response is:
**High water temperatures and water acidity cause coral polyps to expel algae, causing them to turn white in color.**
This process leads to coral bleaching, as the algae (zooxanthellae) provide the coral with nutrients and give them their color. When stressed by high temperatures or changes in pH, corals expel these algae, resulting in the loss of color and vital energy sources.
