Answer:
D. provided jobs and helped Germany out of the Depression
Step-by-step explanation:
Shortly after World War 1 and the signing of the treaty of Versailles, Adolf Hitler engaged in a subtle rearmament of his soldiers. He disguised the project of rebuilding the German army because he was clearly violating the treaty of Versailles which stipulated that Germany disarm its military.
Because Germany disguised the rearmament effort so well, they were able to reinforce their soldiers and eventually launched an attack on unsuspecting neighbors, France inclusive. The rearmament period offered a lot of job opportunities for the German citizens especially those in the technology and aeronautics industry.
