Of the answers that you give here, the best is A because this is the goal of the women's rights movement that continues to be the most controversial today. All of the other answers here (with the possible exception of C, depending on what that option is supposed to mean) were major goals of the women's rights movement. However, none of them except for A continues to have much salience today.
In the US today, the idea that women should not be discriminated against is widely accepted. It is no longer a major issue. The ERA is dead and has not been a subject of discussion for years. Very few people believe that women should be required to be homemakers. That leaves only abortion which is, of course, one of the biggest political issues today.
Of all the choices you listed in your question, the one that is most fiercely debated today is the topic of securing abortion rights. The Supreme Court decision of Roe v Wade made it legal to get an abortion in our country. There have been many attempts to overturn this decision since it was made in 1973. There continue to be people who are working to overturn this case. It remains a political issue for the country today. However, this case still stands as the benchmark for allowing abortions to occur.
Many states have passed laws that restrict a woman’s opportunity to get an abortion. Some states require a waiting period before a woman can get an abortion. In some cases, counseling is required before an abortion can be done. Some states are also requiring that a woman has an ultrasound before the having the abortion.
Thus, securing abortion rights remains a highly debated issue in our country. Answer A is the most appropriate response to this question.
