Final answer:
Sue's coordination of a public education initiative for preventing child abuse at the Northside family agency is an example of a Macro-level intervention, which targets larger populations and societal change rather than individual treatment.The correct option is A.
Step-by-step explanation:
The activity described in the question, where Sue coordinates a public education initiative for preventing child abuse as a social worker at the Northside family agency, represents a Macro-level intervention. This is because the initiative targets a larger population and aims to address child abuse on a community or societal level, rather than focusing on individual therapy or medical treatment. The intervention is designed to create change by educating the public and potentially influencing policies or social norms. Macro-level intervention strategies can include public health campaigns, policy advocacy, and community education programs, which are different from micro-level interventions that involve direct work with individuals or small groups.
