I believe the answer you are looking for is letter B. The CCC was responsible for fixing up forests and were huge advocates for conservation and national park building. Hope this helps.
The main long effect of the CCC was that new forests and improved lands flourished around the nation.
In an effort to reduce the impact on the economy of the Great Depression, President Roosevelt approved a series of measure which was part of his “New Deal”. One of these measures included the Emergency Conservation Work Act (ECW) better known as the Civilian Conservation Corps (CCC). Its main objective was to offer work relief to millions of young men employing them on environmental projects.
The CCC, popularly known as <em>Roosevelt's Tree Army</em> was credited with the reforestation of an estimated three billion trees from 1933 to 1942.
