Which diagram could be used to prove △ABC ~ △DEC using similarity transformations?

Triangle A B C is reflected across side A C and then is dilated to form smaller triangle D C E.
Triangle A B C is reflected, translated to the left, and then is dilated to form triangle D C E.
Triangles A B C and D E C are shown. The angle measures differ between the 2 triangles.
Triangles A B C and D E C are connected at point C. The triangles are shaped differently.
