All side lengths of ΔJKL equal 2 units. A transformation maps ΔJKL to ΔJ'K'L'. The length of side J'K' is 5 units. Is this a rigid transformation?

A
No, there is no one-to-one mapping of all the points of the pre-image to the image.
B
No, at least one segment length is not preserved, making this a nonrigid transformation.
C
Yes, the vertices of the pre-image map to the vertices of the image.
D
Yes, all of the side lengths of the pre-image are proportionate to the image.
