A student performs two trials of a walking experiment on a flat, horizontal field. In Trial 1, the student walks a distance \(L\) due east and then a distance \(L\) due north. In Trial 2, the student walks a distance \(1.5L\) due east and then a distance \(0.5L\) due north. Let \(D_1\) and \(D_2\) represent the magnitudes of the net displacement for Trial 1 and Trial 2, respectively. Which of the following correctly compares the magnitudes of the displacements and provides a valid justification?
