In this question, we are asked to determine which explanatory variable(s) is/are individually significant at the 5% significance level. Individually significant means that the p-value for each coefficient is less than 0.05. From the given regression results, we can see that the p-values for the coefficients of , _x₁, x₂_{are all less than 0.05. Therefore, we can say that}, _x₁, and x₂_{are individually significant at the 5% significance level. Thus, the correct choice is C.}
