Correct answer

B. Closed type of circulatory system

Step-by-step solution

Phylum Arthropoda is characterized by the presence of jointed appendages, a chitinous exoskeleton, and an open circulatory system. In an open circulatory system, blood is pumped out of the heart and the cells and tissues are directly bathed in it. Excretion in many arthropods takes place through Malpighian tubules. Therefore, a closed type of circulatory system is not a feature of arthropods. Answer: Closed type of circulatory system
