Answer:
C. Reflection across the line x=3
D. Reflection across the line y=2
Explanation:
Rotating ABCD through 90 degrees will carry it away from the first quadrant.
Translating ABCD will carry it away from its original position.
Reflecting ABCD across the line x=3, will carry it onto itself because x=3 is a line of symmetry of ABCD
Reflecting ABCD across the line y=2, will carry it onto itself because y=2 is also a line of symmetry of ABCD.
The correct options are C and D
