Answer 1

The correct option is D Comb plates and colloblasts

The correct answer is D , (comb plates and Colloblasts)

explanation: Comb jellies belong to ctenophora and Jelly fishes belong to Cnidaria, In case of comb jellies locomotion takes place by the presence of 8 cillary comb plates on body surface. These comb plates are not found in Cnidaria.

The tentacles of the ctenophores possess some adhesive cells called as colloblast cells or also called lasso cells, these are not present in the Cnidaria.
