Read the Following Scenario and Answer the Question Below

Read the following scenario and answer the question below.
Glass Lake, located in a valley in low forested mountains, for many decades of the 19th and early 20th centuries was a favorite picnic, recreation, and fishing site for people in surrounding towns and farms. However, in the middle of the 20th century, a trend began in which the privately-owned farms in the Lakeʹs watershed were purchased by large agribusinesses.
The decision was made to grow a profitable crop. The demand for quality farmland resulted in the sale of most of the family-owned establishments and a large increase in the area of land under cultivation. Most of the forests were cut to acquire the land needed for crops. The use of chemical fertilizers and pesticides increased several fold by the end of the century. In addition, the combined population of the lakeside villages quadrupled during the same time. The lake experienced a slow degradation of water quality and biodiversity. Sport fishing declined and the lake became murky while the sediments in the lake increased in depth.
-A task force composed of water quality chemists, environmental landscape experts, townspeople and corn growers meet and share information. They decide that they must focus on in the initial efforts to restore the lake.

A) banning agriculture from the entire region
B) reducing fertilizer inputs into the lake by exploring alternative farming techniques, increasing the efficiency of the wastewater plant and using aerators to increase oxygen levels in the areas where streams flow into the lake
C) closing the wastewater treatment plant and reducing agriculture by 75%
D) restoring biodiversity to the deforested areas and closing the wastewater plant
E) reducing the population of the town by 50% and agriculture by 50%
