Sam uses a simulation to explore conservation tactics that will preserve forest resources and provide a sustainable source of wood. In the simulation, the forest has a regeneration rate of 40 years. Which of the following tactician the simulation is most likely to preserve the forest while providing the most wood? A. Log and replant 1/4of the forest every 20 years.
B. Log and replant 1/4 of the forest every 5 years.
C. Log and replant 1/4 of the forest every 10 years.
D. Log and replant 1/4 of the forest every 15 years.

Since A is for 80 years, And D is for 60 years what’s the answer for 40 years?
