Solution

The correct option is D Cordata
Notochord is a mesodermally derived rod-like structure formed on the dorsal side during embryonic development in some animals. Animals with notochord are called chordates and those animals which do not form this structure are called non-chordates. Phylum porifera, coelenterata and platyhelminthes are non-cordates.
