Best answer

Answer: 2. (a) (iv), (b) (i), (c) (ii), (d) (iii)

Key idea: Match each feature with the animal.

  • Gregarious polyphagous pest: Locusta (iv)
  • Adult radial, larva bilateral: Asterias, a starfish (i)
  • Book lungs: scorpion (ii)
  • Bioluminescence: Ctenoplana, a ctenophore (iii)

So (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii): option 2.
