c.

this nonfatal disease is characterized by severe memory loss.

d.

D) Multiple Sclerosis is a disease disrupting the central nervous system. The disease is characterized by the body's immune system attacking and disrupting myelin, the protective sheath covering cells of the brain and spinal cord.
