The plant known as Toxicodendron radicans is commonly called poison ivy, which can cause an allergic skin rash and is the correct answer to the question. Therefore, the correct answer to the question is A) Poison Ivy.
Step-by-step explanation:
The plant Toxicodendron radicans is commonly known as poison ivy. It is a plant native to North America that can cause a skin rash if touched, due to a chemical it produces.
While the name belladonna or deadly nightshade might suggest nocturnal growth because of the term "nightshade," it is actually poison ivy that is being described here.
Belladonna, which is from the genus Atropa, is an entirely different plant known for its toxic berries and historical use to dilate pupils, which can be fatal when ingested. Therefore, the correct answer to the question is A) Poison Ivy.
