The social science that involves studying legal policies is D. law.

To arrive at this answer, we can break down the question and examine the options. The question asks about a social science discipline, which narrows down the choices to political science, history, economics, and law.

Political science primarily focuses on the study of political systems, behavior, and institutions, which may involve analyzing legal policies as part of the overall political landscape. However, it is not solely dedicated to studying legal policies.

History deals with the investigation and interpretation of past events, developments, and their consequences. While legal policies may be a part of historical analysis, it is not the core focus of the discipline.

Economics involves the study of the production, distribution, and consumption of goods and services. While economics may analyze the impact of legal policies on economic activities, it does not encompass the comprehensive study of legal policies.

Law, on the other hand, is the field that specifically concentrates on the study, interpretation, and enforcement of legal systems, including legal policies. It analyzes the creation, application, and implications of laws, regulations, and legal frameworks.

Therefore, the correct answer is D. law since it directly addresses the study of legal policies.
