Explanation:
The odd one out in this list with respect to weed is option C: Parthenium argentatum. Here's why:
Lantana camara:
- Lantana camara is a species of flowering plant commonly known as lantana.
- It is considered a weed due to its ability to spread rapidly and outcompete native plants.
- It is known for its attractive flowers and is often used as an ornamental plant.
Eichornia:
- Eichornia is a genus of aquatic plants commonly known as water hyacinths.
- It is considered a weed in many regions due to its invasive nature.
- Water hyacinths can quickly cover water bodies, blocking sunlight and depleting oxygen levels, which can have detrimental effects on the ecosystem.
Parthenium hysterophorus:
- Parthenium hysterophorus, also known as congress grass or carrot weed, is a highly invasive weed.
- It is native to the Americas but has spread to many other regions, including Asia and Africa.
- It can outcompete native plants and negatively impact agriculture and human health due to its allergenic properties.
Parthenium argentatum:
- Parthenium argentatum, commonly known as guayule, is not classified as a weed.
- It is a perennial shrub native to the southwestern United States and northern Mexico.
- Guayule is cultivated for its latex, which is used in the production of natural rubber.
Therefore, option C: Parthenium argentatum is the odd one out in this list as it is not classified as a weed, unlike the other options.
