Answer:
The correct answer is: C) diffusion.
Explanation:
All of the other three options are means of cellular locomotion.
Cilia are organelles found in eukaryotic cells with the specific function of motility. Cilia have the shape of a slender protuberance and tend to be much larger than their cells.
Flagella are a type of cilia so their function is locomotion as well. Flagella tend to locate in more specific cells, like spermatozoids.
Cytoplasmic streaming is the movement of the fluids inside the cytoplasm.
Diffusion, however, has nothing to do with cellular locomotion. Diffusion is a type of transport that involves molecules such as ions or oxygen.
