The correct answer is 1) National Organization for Women.
The National Organization for Women is a political activist group that fought for gender equality in America. This organization fought for equality in the workplace, considering that men and women completing similar jobs made very different wages. At this time, men got paid a much higher salary in comparison to a woman who worked at a similar occupation. That's why this law was created, in order to minimize the unequal treatment of women in the work place.
