b.

c.

d.

e.

The correct answer is option A, that is, introduction of a predator species.

Explanation:

Any kind of living species like an amphibian, a plant, insect, bacteria, fungus or fish that are not native to an ecosystem and results in destruction is known as an invasive species. They can impart harm to the health of a human being, surrounding, or even to the economy of the nation. An essential factor that converts the species into an invasive one is the non-presence of predators in the novel surrounding. Therefore, the presentation of a predator species would possibly assist in imparting a check in the development of the invasive species.
