Correct Answer

Solution

Natural selection is the phenomena which states that evolution creates variations which act as a heritable trait and occur generation after generation. Individuals with characteristics which increase their probability of survival will have more opportunities to reproduce and their offspring will also benefit from the heritable, advantageous character. So, over time, these variants will spread through the population.
Therefore, the correct answer is option D.
