(Prevalent) disease

  • A.Dangerous
  • B.Contagious
  • C.Fatal
  • D.Widespread

Answer: D

A prevalent disease is a widespread one.

Prevalent means widely existing or common at a particular time or place; the prevalence of a disease is the proportion of a population that has it. So a prevalent disease is one found widely.

Contagious describes how a disease spreads (by contact), not how common it is, and a contagious disease may be rare. Dangerous and fatal describe how serious a disease is, which has nothing to do with how widely it occurs.
