The National Labor Union was a distinctly different type of union from other unions because it worked toward:

A) Producer and worker cooperatives.
B) Creating a national labor political party.
C) Better education.
D) Work hours reform.

The National Labor Union was distinctive in its focus on creating a national labor political party, which would represent the interests of workers and advocate for labor rights in government. This is different from other unions, which often focused on specific industries or trade issues. While the other options (producer and worker cooperatives, better education, and work hours reform) were certainly part of the NLU's agenda, its primary goal was political representation and advocacy.
