Which of the following does not suggest a macro approach in India?

This is because the macro approach focuses on the overall economy and larger economic issues, such as measuring economic growth, inflation, and employment rates, whereas identifying the causes of a particular company's failure is a micro-level issue.

Determining the GNP of India and identifying the causes of inflation in India are both macro-level issues that involve measuring the overall performance of the economy. Analyzing the causes of the failure of industry in providing large-scale employment is also a macro-level issue because it involves understanding the broader economic factors that affect employment rates in the industry.

Therefore, the correct answer is (b) Finding the causes of the failure of X and Co.
