Exponential smoothing with a smoothing constant of 1/3 will create a smoothed series that includes all the original data points plus additional smoothed values for each subsequent period. Since there are 6 data points in the original series, the smoothed series will also have 6 values, including the starting value. Therefore, the answer is D.
