The correct option is Rauwolfia vomitoria
Explanation
The question pertains to Genetic, which refers to the variation of genes within a single species. This diversity allows a species to adapt to different environmental conditions and results in variations in physical traits or chemical compositions across different populations of the same species.Detailed Analysis:
- Rauwolfia vomitoria (Correct): This medicinal plant is found growing in different ranges of the Himalayas. It serves as a classic example of genetic diversity. The plant exhibits significant genetic variation in the potency and concentration of the active chemical reserpine, which it produces. Reserpine is widely used in modern medicine to treat high blood pressure (hypertension) and certain mental disorders.
- Cinchona officinalis (Incorrect): This plant is the source of quinine, which is used to treat malaria. While it is a medicinal plant, the specific context of genetic diversity regarding "reserpine" does not apply here.
- Digitalis purpurea (Incorrect): Commonly known as foxglove, this plant produces digoxin and digitoxin, which are used to treat heart conditions (such as heart failure). It is unrelated to reserpine.
- Papaver somniferum (Incorrect): Known as the opium poppy, this plant is the source of alkaloids like morphine and codeine, used for pain relief. It does not produce reserpine.
Key Takeaway:
Genetic diversity within a species can lead to variations in the production of secondary metabolites. Rauwolfia vomitoria is the standard ecological example demonstrating how genetic variation affects the concentration of the medicinal chemical reserpine.
