ABSOLUTELY INCORRECT .Snails(molluscs) Exhibit Billateral Symmetry(@ free wikipedia) But Do Not Have Chitinous Exoskeleton : Snails Have Hydrostatic Skeleton Filled In Their Homocoels(body Cavity). Chitin (found Only In Arthropods e.g:insects,milipedes,etc) Can Only Be Seen In A Snail's Shell(note:shell is not their skeletal system).Therefore,the Correct Ans:B.
