When a 12-year-old expresses discomfort regarding her older sister's relationship with an 18-year-old boyfriend, the most appropriate action involves considering the safety and wellbeing of the minor involved. Calling Child Protective Services (CPS) can be a critical step if there is a concern that the relationship might pose a risk to the younger sibling, especially given the age difference and potential power dynamics in such relationships.

This option ensures that trained professionals can investigate the situation more thoroughly to assess any potential abuse or risk factors that may not be immediately apparent. The goal is to protect the welfare of the minor, which is a priority in any situation that raises red flags about relationships involving significant age differences, particularly when one party is a minor.

Other options, such as involving parents or directly confronting the sisters, may not adequately address underlying issues of safety. These actions could lead to complications or lack of proper support for the younger sister, who has already indicated discomfort. Additionally, suggesting to "find out if they are having intercourse" could be inappropriate as it places an undue burden on the child to disclose intimate details regarding the relationship, rather than ensuring her safety and comfort first.
