Answer: (C)

The author indicates that economic research evolved during the early 20th century by emphasizing an increased interest in the role of consumer demand. This evolution reflects a significant shift in economic thought, where scholars and researchers began to recognize that consumer preferences and demand dynamics were crucial for understanding market behavior and economic outcomes. This focus marks a departure from earlier economic theories that often prioritized production-related factors over consumer behavior.

By concentrating on consumer demand, the author suggests that economists started to analyze how consumer choices and needs influenced not only what goods were produced but also how production systems and pricing strategies developed in response. This shift connects to broader trends in the economy, where understanding consumer behavior became essential for businesses and policymakers alike. This perspective helped pave the way for modern economics, especially in the areas of microeconomics and market analysis.
