D Correct answer
Explanation

Natural system of classification is based on both phylogeny (evolutionary relationships) and morphology (physical characteristics and structure). Phylogeny shows evolutionary history and relationships, while morphology provides observable traits that help in classification. Modern taxonomy uses both - morphological features provide practical identification methods, while phylogenetic analysis reveals evolutionary relationships and common ancestry.
