Answer: Commonly known as deadly nightshade, belladonna, devil's cherry, and dwale. One of the most toxic plants found in the Western Hemisphere, all parts of the plant contain tropane alkaloids – as do those of its equally deadly sister species A.
Explanation: It contains several toxic alkaloids including coniine and is poisonous to humans and livestock. Consumption of just a small amount of any part of the plant can cause respiratory paralysis and death. Poison hemlock, with its purple-blotched stems, can cause paralysis if ingested.
The first and last sounds most reasonable, but I will go with the last one.
I believe C- photosynthesis but I could be wrong.
