Which of the following is categorized as an exotic weed?

Honeysuckle is categorized as an exotic weed because it is not native to the region where it is found and has been introduced from other areas. Exotic weeds often outcompete native plants for resources such as sunlight, water, and nutrients, which can disrupt local ecosystems and lead to a decrease in biodiversity.

Ragweed, crabgrass, and dandelion, on the other hand, are considered to be either native or naturalized plants that have established themselves in various environments. Although these plants can become problematic in some situations due to their growth patterns, they do not fit the definition of an exotic weed, which is primarily focused on species that have been imported from other regions and can cause ecological harm.
