(D) An open circulatory system is characterized by blood flowing into open spaces or sinuses (hemocoel). This is typical of most arthropods (like $Aedes$ mosquitoes) and hemichordates (like $Balanoglossus$ and $Saccoglossus$).$Nereis$ belongs to the phylum $Annelida$. Annelids are characterized by a closed circulatory system,where blood flows through a network of closed vessels (blood vessels and capillaries).
