Which law guarantees universal access to methods such as sexual education?

The Responsible Parenthood and Reproductive Health Act of 2012, known as RA 10354, is the law that guarantees universal access to methods of family planning and education, including sexual education. This legislation was established to promote responsible parenthood, ensure access to health care services, and provide information on family planning methods. It emphasizes the importance of educating citizens about reproductive health rights, making it crucial for individuals to have reliable knowledge about sexual health and responsible decision-making related to reproduction.

The other options, while important in their respective areas, do not specifically focus on sexual education and reproductive health access. The Consumer Act, for instance, primarily deals with protecting consumer rights and ensuring fair trade practices. The Traditional and Alternative Medicine Act concentrates on the promotion and regulation of traditional and alternative healthcare, and the Magna Carta of Women promotes women's rights but does not specifically address reproductive health education in the same comprehensive manner as RA 10354. Therefore, the focus on universal access to sexual education firmly establishes RA 10354 as the correct response.
