Well, what are the options?
B is the correct answer. When looking at these answers, you have to think about whether or not this seems like something that would have been one of the goals of the women’s right movement.
With answer A, it’s unclear. This could be related to women’s rights, but considering that gender or women are not mentioned, it’s unlikely.
With answer B, it is clear that this is about gender equality, which is what specifically the women’s rights movement was fighting for. This answer is correct.
With answers C and D, it is similar to answer A. Both are improvements to equality, but are not gender or women specific, so it is unlikely that is was done by the women’s rights movement.
