The correct answer is: A. minus end; dynein

Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.

Necessary proteins for the vesicle’s movement are motor proteins:

• kinesin  which is positive end directed

•  dynein which is negative end directed

So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.
