Answer: C.) Cladistics is based purely on the shared characters between organisms and their ranking in evolutionary history.

Phylogeny is the evolutionary science which derives a relationship among the ancient species with their descendants based upon common genetic, physiological and morphological characteristics.

A clade is sufficient to include the organisms in a phylogenic tree based upon their evolutionary history.
