C) Ascaris and Ancylostoma – Metameric segmentation
D) Sea horse and Flying fish – Cold blooded (poikilothermal)
Explanation
[Solution from source] The sea horse and the flying fish are both bony fishes and therefore cold-blooded (poikilothermous). Ornithorhynchus lays eggs, unlike the viviparous bat Pteropus; the crocodile has a four-chambered heart; and Ascaris and Ancylostoma are unsegmented roundworms. Answer (4).
