D Correct answer
Explanation

Fast axonal transport relies on microtubule tracks and molecular motors: kinesin (anterograde transport) and dynein (retrograde transport). Microfilaments (actin) participate in slow axonal transport. Neurofilaments are structural intermediate filaments that provide cytoskeletal support and do NOT participate in active transport.
