Answer:
The correct answer is D. The New Deal's support for organized labor was best shown by establishing the right of collective bargaining.
Step-by-step explanation:
The National Industrial Recovery Act was approved in the framework of the New Deal by Congress in 1933, to introduce two types of reforms. On the one hand, it encouraged industrialists to sign codes of fair competition, and on the other hand, it granted workers the freedom to organize and negotiate collective agreements. The law created both a regulatory body, the National Recovery Administration (NRA), which encouraged the accession of societies. The NRA also contributed by creating jobs in order to fight unemployment.
