Natural selection is the process in which species adapt and change to survive in different environments.
There are four factors that lead to natural selection:
- Variation: this factor refers to genetic variation, it indicates that some individuals within the population have or develop better traits suited to the environment.
- Inheritance: this factor refers to the ability to pass the traits that allow survival to the next generations.
- Selection: refers to the differential survival and reproduction of the individuals
- Time: The changes that occur due to natural selection occur over time and through many generations.
Considering these factors, the correct option is option D.
