Answer: D) keep the area planted with early-successional species.
Explanation: Early successional species grow fast and spread their seeds rapidly and widely. This could help to bring in a potentially high crop yield.
It likely is not A because overplowing leaves the soil susceptible to erosion and damages the physical infrastructure.
B should not be the answer because consistently planting the same crop year-round can deplete the nutrient resource said crop relies on. It’s why crop-rotating is a thing now.
I hope this helps :(((
