Why not B and Why C

however, this proposal also continued to (40) define women in terms of their roles in the domestic . sphere and as mothers. . That neither proposal was able to envision a . system of education that was fully equal for women, . and that neither was adopted into law even as such, (45) bespeaks the immensity of the cultural and political . obstacles to egalitarian education for women at the . time. I understand that the Author does not make a moral judgement about the proposals however, she does seem to hint through her tone that the proposals fall short to a extent. I did not pick up that she thought the Proposals where meant to do as much as feasible at the time, she seems more. Please help me understand?
