• A. A-ii, B-iii, C-v, D-iv, E-i
• B. A-ii, B-v, C-iii, D-iv, E-i
• C. A-i, B-iii, C-v, D-iv, E-ii
• D. A-i, B-v, C-iii, D-iv, E-ii

Answer 1

The correct option is C A-i, B-iii, C-v, D-iv, E-ii

• The body of Porifera (sponges) is organized in such a way so that they form a complex system of pores and canals called the canal system. This system helps in regulating the flow of water within them, e.g., Sycon.
• Aschelminthes possess a muscular pharynx. e.g., Ascaris.
• Annelids possess metameric segmentation in the body, e.g., the earthworm.
• Arthropods possess jointed appendages in each segment of their body, e.g., Cockroaches.
• Echinodermata possess a water vascular system or ambulacral system, e.g., Starfish.
  

So the correct answer is option C.
