Which plant is described as causing a rash when its leaves contact the skin?

• A. It is Poison Oak which causes a rash if the leaves come in contact with your skin
• B. It is a new strawberry type with foliage that is edible
• C. It is Trifolium glabra which causes hair to grow on humans who touch it
• D. It is Poison Oak which is used in flower arrangements as foliage filler

Answer: (A)

Plants that trigger a rash on contact usually do so because they contain an oily resin that sticks to skin. Poison Oak fits this description because its leaves carry urushiol oil, which transfers to the skin on contact and causes an itchy, blistering rash. The other options don’t describe plants known to cause this kind of dermatitis—one mentions edible foliage, another an unlikely hair-growth effect, and the last wrongly suggests it’s used as foliage filler. So the plant described is Poison Oak due to the urushiol-triggered skin reaction.
