Why Was It Mostly Women Who Advocated for Child Laborers

Why was it mostly women who advocated for child laborers in the early 1900s?

A) Women are naturally more caring and attentive to children than men.
B) Men made more money than women, so they did not have to worry about working conditions for themselves or others.
C) Many women suffered the same hardships as child workers, so they empathized and wanted to change conditions for all workers.
D) All of the women advocates were mothers and laborers themselves, so they stood to gain from reforms for themselves and their families.
