Faster

Your Answer
D

Moderate


Solution

The correct option is B

Faster


Conduction of impulses in Myelinated neurons is faster than UnMyelinated neurons . This is because myelin forces  the action potential to jump from one node of Ranvier to the next.   Na+ channels accumulate in the nodes of Ranvier In large myelinated axons, the conduction can be as much as 100 m/sec,or   220 miles per hour.The propagation speed is slower in small, unmyelinated fibers.
