The coefficient of determination (R-squared) is defined as the proportion of variance in the dependent variable (y) explained by the independent variable (x). It is calculated as R-squared = 1 - (SSE/SST). Substituting the given values, we get R-squared = 1 - (1.9/6.8) = 0.7206. Therefore, the best choice is C.
