Refer to the figure below showing a time-lapse series of vesicles being moved along a cytoskeletal structure in the direction of the arrow.The minus (‒)and plus (+)ends of the cytoskeletal structure are indicated.The most likely explanation for the movement of the vesicles is that they are being moved along a(n)_______ by _______.
A) intermediate filament such as a hair;the flowing movement of the cytoplasm
B) microfilament;cytoplasmic streaming
C) actin microfilament;a motor protein such as myosin
D) microtubule;a motor protein such as kinesin
E) microtubule;a motor protein such as dynein
