The presence of the interaction terms (e.g. F1F1F1S1βF1F1F10₂x²) indicates that this is a second-order model. Also, there is only one predictor variable x, so it is a model with one predictor variable. Therefore, the correct answer is C, a second-order model with one predictor variable.

The Model Y = β\betaβ 0 β\betaβ 1x β\betaβ 2x2 ε\varepsilonε

The Model Y = $\beta$ ₀ $\beta$ ₁x $\beta$ ₂x² $\varepsilon$
