Which statement justifies whether or not the two quadrilaterals are congruent?
O A. Yes, because R is the result of reflecting Q across the x-axis.
B. Yes, because R is the result of reflecting across the line y = x.
OC. No, because R can only be obtained from Q by a series of rigid transformations.
OD. No, because R cannot be obtained from Q by a series of rotations and translations.
OE. Yes, because R is the result of rotating Q by 90° counter-clockwise about the origin.
