Which of the following pairs is correctly matched?
Show answer & explanation
Correct answer: C
Explanation
Answer: Macroeconomics - National Income.
Detailed Explanation
Economics is broadly divided into two branches: Microeconomics and Macroeconomics. The key to distinguishing them lies in the "scale" of the study.
Microeconomics (Small scale): It focuses on individual agents and markets. It studies how a specific person, household, or firm makes decisions.
Incorrect Pair: "Microeconomics - Inflation rate" or "Microeconomics - GDP" are wrong because these affect the whole country, not just one individual.
Macroeconomics (Large scale): It deals with the performance, structure, and behavior of the entire economy as a whole.
Correct Pair: Macroeconomics - National Income. National income is the total value of all goods and services produced by a country; hence it is a "macro" variable.
