Answer 1

The correct option is A (b), (d)

A) In (b), Sea Urchin belongs to class Echinoidea and has Aristotle's lantern. So, (b) is correct. In (d), Venus flower basket (Euplectella) belongs to class Hexactinellida and has siliceous spicules. So, (d) is correct.

B) (d) is correct. In (a), Pinctada (pearl oyster) belongs to class Bivalvia. So, (a) is incorrect.
