12. Which of the following terms is defined as the period of a nation's business cycle characterized by increasing gross domestic product (GDP)?

Answer: C

Explanation:

Expansion

The term defined as the period of a nation's business cycle characterized by increasing gross domestic product (GDP) is Expansion. During this phase, economic activity rises, leading to growth in output, employment, and consumer spending.

A) Peak

The Peak refers to the highest point of the business cycle, where the economy is operating at maximum output before a downturn begins. While it represents a strong economy, it does not specifically denote a period of increasing GDP, as it is the culmination of growth rather than the growth itself.

B) Trough

The Trough is the lowest point in the business cycle, marking the end of a recession and the transition to recovery. This phase indicates a decrease in economic activity and GDP, thus it does not align with the definition of a period characterized by increasing GDP.

C) Expansion

Expansion is the correct choice as it defines a phase of the business cycle where GDP is on the rise, indicating economic growth. This period is characterized by increased production, employment, and consumer demand, making it synonymous with an upward trend in the economy.

D) Contraction

Contraction is a phase where economic activity declines, leading to a decrease in GDP. This term contrasts with the concept of expansion, as it signifies a downturn in the business cycle rather than growth.

Conclusion

Expansion is definitively the correct answer as it accurately describes a period of increasing GDP within the business cycle. In contrast, Peak, Trough, and Contraction signify other phases that do not reflect growth, highlighting the unique characteristics of the Expansion phase in economic terms.
