RMSE (Root Mean Square Error) measures the difference between actual and predicted values of the data. The formula for RMSE is Square Root of [(Σ(Predicted_Value - Actual_Value)^2)/n], where n is the number of data points. Using this formula, and rounding the forecast values to 3 decimal places, we get RMSE = 1,006.99. Therefore, the correct choice is C.
