Which of the Following Statements Concerning Propagation of Action Potentials

Which of the following statements concerning propagation of action potentials is NOT correct?

A) Saltatory conduction occurs in myelinated nerve fibres.
B) During conduction by local current flow, there is a flow of current between the active and the adjacent inactive area of the cell membrane, thereby decreasing the potential in the inactive area to threshold.
C) The action potential jumps from one Schwann cell to the adjacent Schwann cell in a myelinated fibre.
D) Saltatory conduction is faster than conduction by local current flow.
