Solution
All organisms given in the question do not belong to same group . Leech and neries belong to phyllum annelida because they have metamerically segmented body. , 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 phyllum arthropoda as they have joined legs and open circulatory system.
