Is line BC parallel to line MN? Choose the best justification.

Line BC is parallel to line MN because triangle ABC is a dilation of triangle AMN by a scale factor of 4 from point A.

Line BC is parallel to line MN because triangle ABC is a dilation of triangle AMN by a scale factor of 3 from point A.

Line BC is parallel to line MN because triangle ABC is a dilation of triangle AMN by a scale factor of 4/3 from point A.

Line BC is not parallel to line MN because there is no dilation that sends triangle ABC to triangle AMN.
