B) The tree-of-heaven is originally from China. It produces a chemical that prevents other plants from growing around it.
Explanation:
In ecology, a plant is said to be "INVASIVE" if it is FOREIGN or NON-NON-NATIVE to a particular region or area and also poses a great threat to the native species of that region. An invasive species, when introduced into a foreign habitat, heavily competes with the existing local species of that same habitat.
This is the case of the tree-of-heaven, which is originally from China. The tree produces a chemical that prevents other plants from growing around it. Note that this plant species is foreign to the Shenandoah National Park in Virginia as it originates from China. Likewise it harms the local or native species of the park by secreting a chemical that prevents other plants from growing around it. This characteristics portrays a plant that is INVASIVE.
