During the early part of the labor movement, immigrants, women, and african americans

The correct answer is C) were often excluded from membership in local unions.

During the early part of the labor movement, immigrants, women, and African Americans were often excluded from membership in local unions.  

Immigrants, women, and African Americans were mistreated and did not receive the respect human beings deserve because in the early part of the labor movement there was no law that protected them. In this period employers preferred to hire children because they could pay them less money than adults. So the labor movement aimed to protect this practice, to help workers in the fabrics, improve the working conditions, and give health support to workers. But during the early part of the labor movement, immigrants, women, and African Americans were often excluded from membership in local unions.  

The other options of the question were, a) created and led local unions, b) supplied mostly skilled labor to employers, and d) were not allowed to work at unskilled jobs.
