What does AFL-CIO stand for?

The correct answer is the American Federation of Labor - Congress of Industrial Organizations. This organization was formed through the merger of two major labor groups in the United States. It represents a wide range of workers and aims to unify various labor unions under one umbrella to promote the interests of workers in the labor market.

This name reflects the historical context and significance of the labor movement, as it emphasizes collaboration between craft unions (represented by the American Federation of Labor) and industrial unions (represented by the Congress of Industrial Organizations). The correct option captures this important partnership and the mission to advocate for workers' rights and improve their working conditions.

In contrast, the other options do not accurately represent the established name of the organization or misstate its purpose and structure. For example, the term "International Organizations" is not a recognized part of their name, and "Community" instead of "Congress" misrepresents the unifying goal of the organization. Consequently, they fail to reflect the actual history and formation of the AFL-CIO.
