Answer 1

Answer:

C.) Quinine cured malaria.

Explanation:

Quinine was used to treat malaria until 1940's. It was prepared from the bark extracts of Cinchona tree. The first antimalarial compound from its bark was isolated in 1800s. This tree is native to Peru and there is ample evidence which proves that it has been used to treat malaria since 1600s. Quinine was in widespread use until 1940's when new drugs with lesser side effects replaced it.
