An adaptation is a trait that enables an organism to survive and reproduce selects which species live in water or land ensures a particular species’ extinction keeps organisms changing in their environments

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".

Therefore option A, is correct.

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
