Answer 1

The correct option is C Annelida consist of triploblastic, eucoelomate, metamerically segmented, bilaterally symmetrical organism with open circulatory system

Phylum Annelida includes bilaterally symmetrical, triploblastic, truly coelomate and metamerically segmented animals with their body covered with a thin flexible cuticle. Blood vascular system is of the closed type.

Hence option C is the correct answer.
