Explanation:

The Civilian Conservation Corps (CCC) was a New Deal reform program implemented in 1933 by President Roosevelt that provided jobs and a means to earn among the young, unemployed men in the US. This program, which lasted for almost a decade, was a voluntary relief work that was open to young, unemployed men to help the people cope with the effects of the Great Depression.

The CCC provided work to such men with certain required conditions like sending $25 of the $30 to their families, providing shelter, food, and medical resources to the volunteers. Also, the program required them to be healthy and gave them employment for up to 4 periods or 4 years. This program led to the men maintaining a healthy lifestyle and improved their physical conditions, boost their morale, and also provided them with higher chances of being employed outside of the Corps.

The only statement that is not true is that many of the men had criminal records.

d. Many of the men had criminal records.

Explanation:

The CCC was a federally funded organization starting in 1933 under FDR that gave jobs to unemployed male Americans in helping environmental conservation in the nation.
