Option A, enables an organism to survive and reproduce
Explanation:
Adaptation is the mechanism through which an organism become enabled to survive and reproduce in certain environmental condition.
For example - in older days "coil mosquito repellents" were used to kill the mosquitoes but eventually the mosquitoes have evolved and became resistant to the deadly effects of "coil mosquito repellent" . This resistance is a form of adaptation to the existing environmental condition. Thus, from here it is also clear that a species or organism adapts to a changing situation though natural selection process in order to become the "fittest for survival".
This is true because when the temperature is high, the particles move accordingly and move fast. This is why you see water boiling fast instead of slow.
