a.
fertilizer
b.
forestry
c.
deforestation
d.
clear-cutting

The answer is B.) Forestry

Deforestation and clear-cutting are both harmful to the environment and are not beneficiary  for the environmental cost. Fertilizer just causes crops to grow faster, so it has nothing to do with forests. That being said, the logical answer is forestry.
