Which of these statements about inflation is true? Inflation means our money has more purchasing power. Inflation happens when there is not enough money. Inflation is due to low production costs. C Inflation is problematic if unexpected.

The correct answer is: D. Inflation is problematic if unexpected.<br /><br />Inflation refers to the general increase in prices of goods and services over time, leading to a decrease in the purchasing power of money. While some level of inflation is considered normal and even beneficial for economic growth, unexpected or high levels of inflation can be problematic.
