The correct answer is: All cyclostomes do not possess jaws and paired fins.

Cyclostomes belong to the division Agnatha. They are jawless vertebrates without paired fins. The Cyclostomata are the living Agnathans, they are primitive in many respects but specialised in others. In the adult stage, they are parasitic or scavengers on fishes. They have round bodies with laterally compressed or diphycercal tails.
