• A. Aconitum napellus
• B. Dalbergia sissoo
• C. Papaver somniferum
• D. Cannabis sativus

Answer 1

The correct option is B Dalbergia sissoo

Dalbergia sissoo is known commonly as Indian rosewood, is an evergreen rosewood tree. It is native to the Indian subcontinent and southern Iran. Shisham is best known internationally as a premier timber species of the rosewood genus, but is also used as fuel wood and for shade and shelter. With its multiple products and tolerance of light frosts and long dry seasons, this species deserves greater consideration for tree farming, reforestation and agro forestry applications.

After teak, it is the most important cultivated timber tree of Bihar, which is the largest producer of shisham timber in India.

Aconitum napellus is the source of drug aconite. Papaver somniferum is the source of many drugs, including morphine, thebaine, codeine, papaverine, and noscapine. Cannabis sativus is the source of drug marijuana. Thus, the correct answer is option B.
