c. What is the impact of foreign competition on the U.S. auto industry?

Explanation:

Economic theory is divided into two broad areas: macroeconomics and microeconomics.

Macroeconomics discusses large economic aggregates, such as income, inflation, and employment variations. It is an approach that aims to discuss these factors and bring about improvements through economic policies.

In turn, microeconomics deals with micro factors, such as the behavior of consumers and companies, including in relation to competitive structures. Therefore, item (D) deals with microeconomics and not macroeconomics.
