To determine which explanatory variable(s) is(are) individually significant, we need to look at the p-values of each coefficient estimate. If the p-value is less than the significance level (0.05 in this case), we reject the null hypothesis that the coefficient is equal to zero and conclude that the variable is significant. From the table, we can see that the p-values for x₁ and x₂ are both less than 0.05, indicating that they are individually significant. The p-value for x₃ is greater than 0.05, so we cannot conclude that it is individually significant. Therefore, the best choice is C, which includes x₁ and x₂ as individually significant variables.
