Answer 1

The correct option is C A-1 B-3 C-5 D-4 E-2

The body of Porifera (sponges) is organised in such a way, so that they form a complex system of pores and canals called canal system. This system helps in regulating the flow of water within them.

Alimentary canal is complete in Aschelminthes with a well developed muscular pharynx.

Annelidans possess metameric segmentation (metameres) in the body.

Arthropoda possess jointed appendages in each segment of their body.

Echinoderms possess water vascular system which helps in locomotion, capture and transport of food and respiration.
