Why is a plant called Prosopis juliflora often mentioned in news ?
Explanation
Option (b) is correct because *Prosopis juliflora* is an invasive alien species that aggressively outcompetes native flora and depletes groundwater, leading to a significant reduction in local biodiversity. Options (a) and (c) are incorrect as the plant is primarily recognized for its ecological threat rather than any widespread commercial application in cosmetics or pesticides. The core concept being tested is the negative impact of invasive alien species on ecosystem health and indigenous habitats.
