Answer:
A. The NRA set expectations for reasonable working conditions.
Explanation:
As a response to the "Great Depression," President Franklin D. Roosevelt established the "National Recovery Administration" (NRA). This was meant to allow fair competition in the nation. Since the market was unstable during this period, the NRA provided codes that were to be followed for the members (since it was voluntary). These codes included setting minimum wages and the minimum prices of the items that were to be sold. It also controlled the number of maximum hours that the workers will be working weekly. Clearly, it shows that the NRA set expectations for reasonable working conditions.
However, the Supreme Court declared that the NRA breached the separation of powers under the Constitution. So, this stopped the NRA's operations shortly.
