Which set of transformations proves that rectangle ABCD is congruent to rectangle A'B'C'D'?

A.
a reflection of rectangle ABCD across the y-axis, followed by a translation 7 units down
B.
a reflection of rectangle ABCD across the x-axis, followed by a reflection across the y-axis
C.
a translation of rectangle ABCD 7 units to the left, followed by a translation 7 units down
D.
a 180° rotation of rectangle ABCD about the origin, followed by a translation 3 units up

C. a translation of rectangle ABCD 7 units to the left, followed by a translation 7 units down

Jarvis wants to translate rectangle ABCD horizontally by -4 and vertically by +3 to produce rectangle A'B'C'D'. What will be the coordinates of C' after Jarvis completes this translation?
