Explanation : renission and exacerbation of multiple sclerosis are the early onset of symptoms of multiple sclerosis .

c : it can affects adults 20 to 50 years of age .

Explanation : it can affect mostly 20 to 50 years of age but it can also seen in any age .

- option d and e are false as its diagnosis takes longer and is complex , and its course is unpredictable .
