Vedclass · Answer

(D) Insects belong to the phylum $Arthropoda$,class $Insecta$. The most diagnostic feature of insects is the presence of three pairs of jointed legs (total $6$ legs) attached to the thorax. While wings,antennae,and compound eyes are common in many insects,they are not exclusive to them (e.g.,some arachnids have compound eyes,and many other arthropods have antennae). Therefore,the presence of jointed appendages (specifically $3$ pairs of legs) is the defining characteristic.
