An exponential function occurs when the growth rate of a population (or temperature, savings account, etc.) is proportional to the population (or temperature, savings account, etc.) at any time.

In this csse, the answer is b) since temperature changes at a rate that is proportional to the difference between the temperature of the rod and the air.
