Explanation:

1. Analyze the first option: It describes microeconomics (studies individual/firm behavior), not macroeconomics.
2. Analyze the second option: This is personal finance management, not related to macroeconomics.
3. Analyze the third option: Macroeconomics focuses on the entire economy's performance, structure, and large - scale phenomena like growth, employment, inflation, and GDP. This matches the definition of macroeconomics.

Answer:

The third option: the study of an entire economy’s performance, structure, and decision - making, focusing on large - scale phenomena such as economic growth, employment, inflation, and gross domestic product (GDP).
