Gina dilates several line segments by different scale factors and observes their images. Afterward, she claims that the ratio of the length of the image to the length of the original line segment is equal to the scale factor of the dilation. Which statement BEST describes Gina's claim? A. Gina's claim is true for all dilations of all line segments. B Gina's claim is true only for dilations with a positive scale factor. С. Gina's claim is true only for dilations with a scale factor of 1 or -1. D Gina's claim is true only for dilations of line segments passing through the center of dilation.
