PLEASE HELP!
Which transformations will produce similar, but not congruent, figures?
A)Triangle MNO is reflected across the y-axis and then rotated 180° clockwise to form triangle M"N"O" .
B)Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle M"N"O" .
C) Triangle MNO is reflected across the x-axis and then translated 9 units down to form triangle M"N"O" .
D)Triangle MNO is reflected across the x-axis and then rotated 90° clockwise to form triangle M"N"O" .
