I believe that the answer would be A.) Empathy.
Answer:
Discussion, projects, campaigns and events provide a supportive platform to the victims of human right violations not only by spreading awareness and letting people know about it, but also by giving them a platform to report their grievances and get the support of the common mass.
There are many groups or organizations that come forward to help the affected ones by providing proper monetary help or support in some other form.
Providing support to the victims to take action against violations and giving them the right stage to raise their voices is equally important.
