Coelom: Absent,Absent,Absent

Vedclass · Answer

(A) The correct answer is $A$. $1$. Arthropoda,Mollusca,and Chordata are all triploblastic animals and possess a true coelom (coelomates). Therefore,stating that the coelom is absent in all three is incorrect. $2$. Arthropods and Chordates exhibit metameric segmentation,whereas Molluscs are generally unsegmented. Thus,option $B$ is correct. $3$. All three phyla possess a complete digestive system with a mouth and anus. Thus,option $C$ is correct. $4$. All three phyla possess a circulatory system (though the type may vary,e.g.,open in Arthropoda and Mollusca,closed in Chordata). Thus,option $D$ is correct.
