Treating the season as a categorical variable allows us to encode it as distinct levels, making it easier to account for the seasonality in the model. This approach is commonly used in time series analysis to capture recurring patterns in the data. Qualitative variable is a less common term for categorical variable, so B is not wrong, but option A is more specific. C is incorrect as annual variable means something different than seasonal variable.
