The correct answer is option 1, which is 3 years.
To determine this, we need to find the average supply of rice for the years 2008 to 2013 and then identify how many years the supply was more than this average.
However, we are not provided with any data or information regarding the supply of rice for each individual year. Without this data, it is impossible to calculate the average supply or identify how many years had a supply greater than this average.
Therefore, we cannot accurately determine the correct answer based on the information given in the question.
