Answer:
C. Acclimatization
Explanation:
I think of "acclimatization" as acclimating to a new environment, also it's clearly derived from acclimating. It's just another way to say adjusting to the environment, and isn't necessarily restricted to high elevations. It could also be temperature, or humidity. I hope this helped!
I think elevation impacts the temperature at which water boils because...
As the altitude increases the pressure in the atmosphere decreases. This means that when the atmospheric pressure is lower, your water will reach it's boiling point faster. (AKA: at a lower temperature.)
