An interaction term is used when the relationship between the independent variable and dependent variable changes for different values of another independent variable. Therefore, option D is the correct choice. The other options are not related to the use of interaction terms in multiple regression models. An interaction term is used when the relationship between the two independent variables (represented by 11ebc114_12b8_58e7_8acb_bb2fcae3819d_TB8562_11 and 11ebc114_12b8_58e8_8acb_7355653eb177_TB8562_11 in the question) changes for different values of one of the variables, indicating an interaction effect. It is not used in situations where the coefficient of determination is small, there is a curvilinear relationship, or neither independent variable contributes significantly to the model.
