Which best explains whether or not triangle ABC is congruent to triangle LMN ?

A
The figures are congruent because a 180 degrees rotation about the origin and then a reflection over the x -axis will map triangle ABC onto triangle LMN .
B
The figures are congruent because a 270 degrees rotation about the origin and then a reflection over the x -axis will map triangle ABC onto triangle LMN .
C
The figures are not congruent because there is no rigid transformation or combination of rigid transformations that will map triangle ABC onto triangle LMN .
D
The figures are not congruent because point cap b corresponds with point cap n and point cap c corresponds with point cap m .
