The correct answer is C. During deflation, prices fall over time. At first, this may seem good, but it actually causes people to delay spending because they think prices will go down more. For example, a student saving for a laptop might decide to wait a few months hoping for a cheaper price. If millions do the same, businesses earn less, which can lead to job losses and a slower economy. Deflation happened in Japan in the 1990s, and it led to years of very low growth.
