D Correct answer
Explanation

There are a number of new developments in invasive species management. One is the development of new technologies for detecting and controlling invasive species. These technologies include remote sensing, DNA barcoding, and environmental DNA (eDNA) analysis. Another new development is the development of new biological control agents for invasive species. Biological control agents are organisms that are used to control invasive species by attacking them or competing with them for resources. Finally, there is also the development of new policies and regulations to prevent the introduction and spread of invasive species. These policies and regulations include import restrictions, quarantine measures, and public education campaigns.
