The correct option is A Microtubular organization and type of movement
Flagella of prokaryotic and eukaryotic species differ in microtubular organizations and type of movement in eukaryotes, the tubular arrangement is (9+2) and specialized while in prokaryotes the microtubular arrangement is (9+0) and is simple, hence movement is also different, prokaryotes have rotatory movement and eukaryotes have bending movement. Thus, the correct answer is option A.
