The correct answer is: C.Produce many offspring.

A key characteristic of most invasive species is their ability to produce many offspring. This high reproductive capacity enables invasive species to spread quickly and establish large populations in new environments, often outcompeting native species for resources.

Here's why the other options are not generally key characteristics of invasive species:

A.Ability to breathe in the air & in the water: While some invasive species, like amphibians or fish, may be capable of breathing both in water and air, this is not a universal trait of invasive species. Most invasive species thrive in specific environments and don't necessarily need to be able to survive in both.
