To determine the magnitude of dilation, we need to know the coordinates of the original points \( A, B, C, D \) and the corresponding points \( A', B', C', D' \) after dilation. The magnitude of dilation can be found using the formula:
\[ \text{Dilation factor} = \frac{\text{Distance from origin to } A'}{\text{Distance from origin to } A} \]
If you provide the coordinates of the points or any additional information, I can assist you in calculating the dilation factor. Otherwise, without specific coordinates, we cannot determine the correct answer from the options given.
