Respuesta :
I would choose C.
A isn't the best of option because it does not directly mention fresh vs. salt water.
B does not make sense because it is discussing introduced species not native ones.
And D literally just has no relevance.
I would go with C because it is literally drawing attention to introduced species because of dumping ballast waters.
