Explanation:

Recently, a special drive to uproot the invasive Lantana bushes in the Sajjangarh Wildlife Sanctuary in Rajasthan’s Udaipur district has been carried out along with the plantation of native species on the cleared patches of land.

• An invasive species is an organism that is not indigenous, or native, to a particular area and causes harm.
• They are capable of causing extinctions of native plants and animals.
• They reduce (not increase) biodiversity, competing with native organisms for limited resources, altering habitats and negatively affects the ecosystem stability. Hence, option C is correct.
• They can be introduced to an area by ship ballast water, accidental release, and most often, by people.

Hence option 4th is correct.
