Best answer
The correct option is (c) Saltatory Conduction

For explanation: Saltatory comes from the Latin word saltare which means to jump.  In presence of myelin sheath, the nerve impulses are conducted not by depolarizing the adjacent point but by depolarizing the adjacent Node Ranvir. This gives the effect of the impulses jumping and so are called as Saltatory Conduction.
