Answer:

Option C, They have a closed circulatory system

Step-by-step explanation:

Cephalopods belong to phylum Mollusca and are unique in sense that they have a closed circulatory system. This closed circulatory system consists of three unusual hearts with arteries, veins, and capillaries. Excepts Cephalopods, all majority of mollusks have open circulatory system. In open systems, heart pumps blood through blood vessels into the gills and then into body cavities (hemocoels)

Hence, option C is correct

Which characteristic is unique to cephalopods? They have a radula. They can live in water or on land. They have a closed circulatory system. They can produce pearls.
