A)
This translation is rotation
Recall that rotation does not change the size and shape of the figure.
This gives the congruent
B)
By dilation, the size of the figure is reduced.
This gives the similar not congruent.
C)
This translation is rotation
Recall that rotation does not change the size and shape of the figure.
This gives the congruent
D)
This translation is a reflection
Recall that reflection does not change the size and shape of the figure.
This gives the congruent
Hence option B is correct.
