Final answer:
No option listed directly pertains to an organization solely focused on women's rights and gender equality; however, the UN through UN Women and NGOs like CARE International align closely with these objectives.
Step-by-step explanation:
The organization dedicated to promoting women's rights and gender equality, focusing on issues such as education, employment, poverty reduction, healthcare accessibility, and social and political rights, is none of the options listed (a through e) directly. However, elements of the work described can be associated with functions performed by organizations such as the United Nations, particularly through its entities like UN Women, which are committed to gender equality and the empowerment of women. NGOs like CARE International also work towards these goals, though their mandate is broader and includes emergency aid in addition to long-term projects aimed at reducing poverty and injustice. Significant efforts are made by various international and non-governmental organizations (NGOs) to improve opportunity, safety, education, and equality for women globally.
