A sequence of transformations that proves congruence between shape I and shape II by mapping shape I onto shape II is a reflection across the y-axis, followed by a (Blank) , and then a translation 1 unit down.
Alternatively, a sequence of transformations that proves congruence between shape II and shape I by mapping shape II onto shape I is a reflection of shape II about the x-axis, followed by a (Blank) , and then a translation 1 unit left.

Blank 1:
A reflection across the x- axis
B 90 degree clockwise rotation about the origin
C 90 degree counterclockwise rotation about the origin
D 180 degree rotation about the origin

Blank 2:
A reflection across the y- axis
B 90 degree clockwise rotation about the origin
C 90 degree counterclockwise rotation about the origin
D 180 degree rotation about the origin
