Hey there,
One situation that can be caused by both human and nature would be A: Forest fires.
All forest fires need to start is a very small fire. As most trees are very flammable and can catch fire easy. This can be by humans such as a match or a cigarette. Or by nature maybe a lightning strike to start a small fire that would turn into a large one.
B: Would be incorrect because fossil fuels is done by humans. We use it as gas and fuel for various things. And cannot be done randomly by nature.
C: Would be incorrect because humans often resort to large deforestation to get lumber for wood. Usually for houses or other building objectives.
Hope this helps!
