Refer to the figure. Why are thin, stiff pseudopods so useful to the radiolarian below?
A) They increase the surface area of the radiolarian, allowing for phagocytosis of food particles.
B) They allow the radiolarian to float, giving its photosynthetic endosymbionts maximal access to light.
C) They are used to spear prey and immobilize them for saprobic absorption.
D) They play a role in locomotion, allowing the radiolarian to migrate toward nutrient-rich deposits.
E) They help defend the radiolarian from attacks by other protists.
