Which type of organization is focused on a particular cause or issue?

An advocacy organization is specifically dedicated to promoting a particular cause or issue. These organizations aim to influence public policy, raise awareness, and advocate for changes that support their positions on social, political, environmental, or economic matters. Advocacy organizations often engage in activities such as lobbying, public campaigns, and grassroots mobilization to garner support and enact change regarding the issues they care about.

In contrast, professional organizations are typically focused on the interests and development of individuals within a specific profession and may not necessarily center on a particular social issue. Membership organizations involve collective interests and can reflect various focuses, but they are broader in scope. Labor organizations primarily represent the interests of workers and advocate for better working conditions and wages rather than focusing on a singular cause or issue in the wider social context. Therefore, the choice of advocacy organization distinctly aligns with the goal of addressing specific causes or issues, making it the correct answer in this context.
