Vedclass · Answer

(C) $1$. $A$: Cockroach and Locust are Arthropods showing metamerism,but Tapeworm (Platyhelminthes) is acoelomate and does not show true metameric segmentation.$2$. $B$: Liver fluke (Platyhelminthes) is bilaterally symmetrical,but Sea anemone (Cnidaria) is radially symmetrical and Sea cucumber (Echinodermata) shows pentamerous radial symmetry in adults.$3$. $C$: Prawn,Scorpion,and Locusta (Locust) all belong to the Phylum Arthropoda,which is characterized by the presence of jointed appendages.$4$. $D$: Scorpion,Cockroach,and Spider are all Arthropods. While they possess a ventral solid central nervous system,this is a general characteristic of many invertebrates,but the grouping in $C$ is the most definitive morphological classification based on the phylum-level trait of jointed appendages.
