Answer:
A) Burning of fossil fuels

Step-by-step explanation:
Burning fossil fuels is an anthropogenic activity, meaning humans do it. Even though humans can create wildfires, for the most part it is a natural and good thing for soil; humus - dead organic matter - is good for top soil. Flood and Volcanic eruption are both done by mother nature.
