Answer:
The correct answer is C.
Explanation:
In economics, real rate refers to a rate of return that accounts for the effects of inflation, in order to reflect how rates of return have really changed over time. When the rate of inflation is positive (above 0%), the real rate will be less than the nominal rate. For example, if an investment offers a rate of return of 10% per year, but the rate of inflation is 4% during that year, that means the real rate is 6% per year (10% - 4% = 6%).
