The correct option is D Dependent on microfilaments for intracellular circulation
Cytoplasmic streaming refers to rotational movement or streaming of liquid portion of cytoplasm (the cytosol) as mediated by actin filaments of the cytoskeleton. It helps in intracellular circulation of materials in Amoeba. Extracellular digestion in Amoeba is carried out by pseudopodia, not by cytoplasmic streaming. Thus, the correct answer is option D.
