The drug "Belladona" is obtained from:
A. Rauwolfia
B. Atropa
C. Capsicum       
D. Solarium

Answer 1

Hint:  Belladonna is a plant. The roots and leaves are used to produce medicine. Atropa Belladonna is a toxic plant that is also known as deadly nightshade. Its leaves, roots, and fruits include alkaloids: hyoscyamine, atropine, and scopolamine. The risk of poisoning in children is significant due to possible confusion about other fruits.

Complete step-by-step answer:
The name "belladonna" implies "beautiful lady," and was selected due to a dangerous practice in Italy. The belladonna berry juice was used traditionally in Italy to enlarge the pupils of the ladies, giving them a remarkable appearance. This was not a great idea, because belladonna can be toxic. The drug Atropine is extracted from Atropa. Atropa belladonna, an essential medicinal plant is of the family Solanaceae. Atropa belladonna, widely known as the belladonna or deadly nightshade, is a herbaceous perennial plant in the family Solanaceae. The leaves and fruits are extremely toxic and contain tropane alkaloids. These toxins contain hyoscyamine and scopolamine, which cause hallucinations and bizarre delirium.
Rauwolfia alkaloids belong to a common class of medicines known as antihypertensives. They are used for high blood pressure (hypertension).
Capsicum also called chilli pepper or red pepper is a herb. Its fruit is usually applied to the skin for arthritis pain and other disorders. The fruit of the capsicum plant includes a chemical substance known as capsaicin. 
A solarium is any tanning unit that utilises ultraviolet (UV) radiation to tan the skin. Solariums are also called sunlamps, sunbeds, or tanning beds. There is no such thing as a secure tan from a solarium. UV radiation from solariums raises the risk of developing skin cancer.

Therefore the correct answer is Option B.
Note: Belladonna was used in herbal medicine for many centuries as a muscle relaxer, pain reliever, and anti-inflammatory, and cures menstrual issues, histaminic reaction, peptic ulcer disease, and nausea.
