What legislation established minimum wage and maximum hour regulations while banning child labor?

The Fair Labor Standards Act (FLSA) is the correct choice as it was enacted in 1938 to address issues of labor, specifically establishing a federal minimum wage, maximum working hours, and regulations to prohibit child labor. This landmark legislation aimed to protect workers' rights during the Great Depression and maintain fair labor standards across the United States.

By creating minimum wage and maximum hour standards, the FLSA ensured that workers received a basic level of compensation for their labor and that they were not required to work excessively long hours without adequate compensation. Additionally, the act made strides to eliminate child labor, enforcing regulations that limited the types of work children could do and the hours they could work, thereby promoting the welfare and education of young people.

The other options relate to important labor and social welfare legislation, but they do not encompass the specific provisions of establishing minimum wage and maximum hour regulations or banning child labor. For instance, the National Labor Relations Act focuses on labor rights and unionizing, the Social Security Act is centered around social welfare and retirement benefits, and the Wagner Act also emphasizes labor rights but does not address wage and hour standards directly.
