Answer: d. All of the above
Explanation:
Evolution can be define as the change that occur in a particular species over a time. Such changes are because of natural selection of favorable traits responsible for the survival of the organisms under unfavorable conditions.
a. Increasing phenotypic complexity over time: Some of the phenotypic traits make the organism suitable for survival of the species. These traits are transferred to the members of the next generation. This process leads to the development of new species.
b. A change occurring in individuals as a result of selection: The evolution is a change that occur after the process of natural selection as the organism adapts according to the traits they exhibit.
c. Descent with change: The ancestors are the organisms which undergoes changes such changes are transferred to the new generation that is descents.
