An analyst ran three models as follows with the respective training and validation periods error values: 1. Linear Trend; Training Period RMSE =600.56, Validation Period RMSE =502.35 2. Exponential Trend + Seasonality: Training Period RMSE =586.25, Validation Period RMSE =555.24 3. Polynomial Trend + Seasonality: Training Period RMSE =502.69, Validation Period RMSE =70460.25 Based on the above information, please select the right statements below. a. An overfitting issue is present in the exponential trend + seasonality model. b. The exponential trend + Seasonality model has learned the systematic components better than others c. The polynomial trend + Seasonality model can forecast better than others d. The exponential trend + Seasonality model can forecast better than other models. e. An overfitting issue is present in the polynomial trend + seasonality model
