Which plant should be pulled and burned due to its poisonous nature?

• A. Sycamore tree
• B. Yew
• C. Foxglove
• D. Ragwort

Answer: (D)

Ragwort is singled out here because it’s a highly dangerous weed for grazing animals. It contains toxins that build up in the liver and can cause irreversible liver damage, sometimes after the plant is eaten in hay or pasture for some time. The safest, most effective control is to pull the plants up by their roots before they flower and then burn them to destroy the toxins, rather than composting them where seeds could spread or animals could still come into contact with them. Among the other options, sycamore is a tree rather than a grazing weed, and yew or foxglove are poisonous but are not the common pasture plant that needs routine removal in this context.
