The assertion is true, as Cyclostomata refers to a group of jawless fish, including lampreys and hagfish, and they do not possess an exoskeleton. However, the reason is false. The endoskeleton of Cyclostomata is not cartilaginous with bones but is mainly composed of cartilage Hence, the correct option is 3.
