Answer:
[tex]\boxed {\boxed {\sf A. \ Any \ unskilled \ or \ skilled \ worker}}[/tex]
Explanation:
The Knights of Labor was a United States labor organization established in 1869, plus it was the first major union. During this time, factory working conditions were awful and dangerous. Excessively long work days with few breaks and inadequate compensation were common.
Groups like the Knights of Labor wanted to help workers and improve their working conditions. However, this group was unique because it welcomed all genders, races, and workers.
Therefore, every worker (not business owners) was included, not just women or children. The best answer choice is A.
