Solution

Leech and Nereis belong to phylum Annelida because they have a metamerically segmented body, that is, the body is divided into many segments internally by septa. Body segments are lined up one after the other from head to tail.

But Scolopendra, prawn and scorpion belong to phylum Arthropoda as these have jointed legs and open circulating system.
