Answer:
The correct answer is letter "A": the increase in the price of rice.
Explanation:
The Consumer Price Index, or CPI, is considered the American economy's benchmark inflation guide. The CPI uses the basket of goods to assess a stable year-to-year product base placing special attention on the price of products that consumers buy and use every day.
Thus, the CPI will consider the increase in the price of potatoes if that situation happens in a given market.
