Answer:
B - invasive species
Step-by-step explanation:
Invasive species are species that are not native to a particular habitat but are introduced into that habitat intentionally or by accident.
The Burmese python was released in Florida (where it is not a native species). Because it is not from Florida, it does not have any natural predators there, and it can seriously damage the ecosystems by preying on organisms that have no adaptations against the new predator.
