Which plant is incorrectly claimed to cause hair growth on humans who touch it?

• A. Poison Ivy
• B. Strawberry
• C. Trifolium glabra
• D. Poison Oak

Answer: (D)

Touching a plant doesn’t trigger new hair growth in humans; the real issue is skin reactions, not growth. Plants such as poison ivy and poison oak contain urushiol and cause contact dermatitis—itching, redness, and blisters—rather than anything that would promote hair growth. Since the statement in the question claims that touching poison oak causes hair growth, that claim is incorrect, making it the best choice. The strawberry plant and Trifolium glabra aren’t known for any effect that would be described as hair growth from touch, so they don’t fit the misconception.
