Answer: B. to give money to businesses to fund war production.
The Defense Plant Corporation had the primary goal of giving money to businesses to aid the funding of war production. The DPC helped finance the expansion of the industrial sector of The United States to be able to meet up with equipment, materials, and machinery required for war if it eventually comes.
As a subsidiary of the New Deal-era Reconstruction Finance Corporation, the Defense Plant Corporation was started by President Franklin in August 1940 and this somehow boosted the economy of the United States; jobs were made and many Americans went back to work. With the DPC, the industrial capacity of America was increased and this made the United States a stronghold in the production of war materials equipment when needed.
