Answer

Brief Explanations:

In an exponential - decay cooling model like $T(t)=60e^{- 0.1t}+20$, as $t$ (time) approaches infinity, $e^{-0.1t}$ approaches 0. So, $T(t)$ approaches 20. This represents the ambient or room temperature that the coffee's temperature will approach over time.

Answer:

C. The room temperature the coffee approaches over time
