Correct answer
D. Both have segmented body
Step-by-step solution
Segmentation occurs in three highly organized phyla-annelida (earthworm), arthropoda (Periplaneta) and chordates. The body is often divided both externally and internally into a number of segments (metameres) e.g., annelids. Segmentation is mostly external in arthropods and mainly internal in man and other chordates.
