Solution
The correct option is D Oceanic island communities
Some communities such as tropical oceanic islands appear to be particularly vulnerable to invasions. The vacant niche hypothesis suggests that island communities and some others are relatively impoverished in numbers of native species and thus cannot provide biological resistance to newcomers. Hence, they are most vulnerable.
Therefore, the correct answer is option D.
