Answer:

a) After plunging into icy-cold water, Gary's core body temperature rapidly drops.

Step-by-step explanation:

Homeostasis is the process by which our bodies find and reach equilibrium, could be physical or chemical, when you get into icy-cold water, for there to be homeostasis your body should get hotter in order to keep its normal temperature, but often the body tempereature just drops because there´s not much the vody can do against that.

The best answer to the question you have presented above is letter a. The statement that is NOT an example of homeostasis is 'After plunging into icy-cold water, Gary's core body temperature rapidly drops'. This is because it should increase rather than decrease.
