Suppose you run Polynomial Regression Method and that results to 2 models. Both of them are significant (F-test; p-value < 0.05), same with their coefficients. If Model 1's R-square is 0.777 and Model 2's is 0.889, what is the best model to use?*

a. Model 1, because the R-square change of 11.20% is not that large contribution to add more power to independent variable.

b. Model 2, because the R-square change of 11.20% is very significant contribution to model's predictive power.

c. Model 1, even though its R-square is 11.2% lower than Model 2, it will describe monotonic relationship best.

d. Model 2, its R-square is higher than 11.2% than Model 1, it will describe non-monotonic relationship best.
