• A. Datura alba
• B. Rauwolfia vomitoria
• C. Atropa belladonna
• D. Papaver somniferum

Answer 1

The correct option is B Rauwolfia vomitoria

Genetic diversity reflects the variations in genetic composition that exists between individuals of the same species.

Rauwolfia vomitoria is a medicinal plant that grows in different Himalayan ranges. It produces a chemical compound named reserpine which is used for the treatment of high blood pressure.


Different varieties of this plant produce reserpine, which is chemically identical but varies in potency and concentration. This is due to genetic diversity amongst the individuals belonging to the species Rauwolfia vomitoria.

Papaver somniferum is the poppy plant from which opium is extracted.
Atropa belladonna is a perennial herbaceous plant which has hallucinogenic properties. The leaves of this plant were often used as recreational drugs for its impact of vivid hallucinations in the user's mind.

Species of Datura contain tropane alkaloids like atropine and scopolamine. It is used in the treatment of asthma, chronic bronchitis etc.
