Selected Answer: C
Ridge regression extends ordinary least squares by penalizing the size (L2 norm) of the coefficients, but the residual term is still handled the same way as in ordinary least squares—that is, by minimizing the sum of squared residuals. Hence, among the given options, the correct choice is: C. e²
