Solution

The correct option is C III only
Centipedes belong to class Chilopoda of phylum Arthropods. Ventral nerve cord is the backward extension of circumpharyngeal connective that is held together and consists of the segmental ganglion. It is the characteristic feature of phylum Arthropoda. Arthropods have the rigid chitinous exoskeleton that covers their complete body, not a calcium shell. Segmented body and paired, jointed appendages to perform different functions are also features of this phylum. It makes option D correct.
