DO Which transformation most likely maps figure \( A B C D \) onto figure \( A^{\prime} B^{\prime} C^{\prime} D^{\prime} \) ?
(A) Reflection across the \( \mathrm{Y} \)-axis
(B) Rotation \( 90^{\circ} \) Clockwise about the origin about the origin
Confirm rotation
Step 1 :Observe figures
Step 2 :Check transformation conditions
Step 3 :Confirm rotation
