The best classification system is that which most closely a. unites organisms that possess similar morphologies. b. conforms to traditional, linnaean taxonomic practices. c. reflects evolutionary history. d. corroborates the classification scheme in use at the time of charles darwin. e. reflects the basic separation of prokaryotes from eukaryotes.

c.reflects evolutionary history.

Explanation:

The best classification system in biology is that that reflects evolutionary history, this is because more developed animals evolved from ancestors, this means that little modifications on the DNA happened over the course of million of years that created the animals that we know today, so this little differences would be relfected on a classification system.
