Final answer:
Advocacy involves speaking up for specific interests using various tactics, while public policy is the governmental actions and decisions that address societal issues. Option 'c' rightly states that public policy sets laws and advocacy speaks for interests.
Step-by-step explanation:
The question asks how advocacy differs from public policy. Advocacy and public policy are distinct although they may intersect. Advocacy involves speaking up for a particular interest or cause, employing strategies like lobbying, public campaigns, and education to persuade policymakers and the public about the merits of a particular view or action. Public policy, on the other hand, refers to the decisions and actions of government encompassing laws, budgets, and regulations that address issues of collective concern to society. It is strategic, often involves compromises, and includes all the decisions governments make to influence behavior or allocate resources through legislation or other governmental actions.
Answering the original question, option 'c' is correct: public policy involves the setting of laws and recommendations, while advocacy involves speaking up for a particular interest.
