Answer:

A. increase the speed of nerve impulses

Explanation:

Schwann cells speed up nerve impulses by secreting a fatty substance called myelin around the axon of peripheral nerves. (Myelin can greatly increase the speed of impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.)
