• B. The examination of the overall economy and its trends
• C. The analysis of market competition among firms
• D. The focus on the behavior of individual industries

Answer: (B)

Macroeconomics is defined as the examination of the overall economy and its trends. This branch of economics focuses on large-scale economic factors, such as national productivity, total national income, inflation rates, unemployment rates, and economic growth. It seeks to understand how these aggregate indicators interact and affect the economy at a broader level, rather than concentrating on individual businesses or sectors.

The importance of macroeconomics lies in its ability to analyze the performance of an entire economy and to develop policies that can enhance economic stability and growth. This analysis can inform government policy decisions and guide monetary and fiscal policies to promote economic health.

The other options refer to aspects of microeconomics, which investigates individual markets and the decision-making processes of consumers and firms. Specifically, the study of specific business decisions and consumer preferences focuses on microeconomic behavior, as does the analysis of market competition among firms and the behavior of individual industries.
