Which of the following correctly defines inflation?

Explanation

This question is asking about the definition of inflation. Inflation is a term used to describe the increase in prices of goods and services over time. It is measured by the rate of change in the overall price level of a country's economy.

The question provides four options, and you are to choose the option that correctly defines inflation. Option A describes a one-time increase in commodity prices, which is not the same as inflation. Option B describes a period when prices increase rapidly, which is similar to inflation but not the complete definition. Option D describes an increase in the overall level of business activity, which is not related to inflation.

Option C is the correct answer. It defines inflation as a sustained increase in the overall price level. This means that over a period of time, the prices of goods and services in a country's economy continue to rise. Inflation can have both positive and negative effects on an economy, depending on several factors such as the rate of inflation, the causes of inflation, and the actions taken to manage it.
