Economics is a social science that studies how individuals, organizations, and societies allocate scarce resources to meet their unlimited wants and needs. It focuses on the production, distribution, and consumption of goods and services. Unlike physical sciences, economics deals with human behavior, which is often unpredictable and influenced by cultural, social, and political factors. Economics also includes the study of government policies, international trade, and financial markets, among other topics. Therefore, the correct answer is social science.
