Answer:
The answer is A. The working class was becoming more organized as time went on.
Step-by-step explanation:
The working class gradually started to realize that if they are not going to be exploited and need their voice to be heard, they have to organize and put a join effort as individually, not anyone can put a resistance against the unfair and unequal practices of the industrialists and their employers.
because of this, many working class citizens unionized and gathered around their unions to demand what they needed. As a result, many unions were created during and after this era.
