Which transformation was applied to figure A to form figure B?

A.
Figure A was rotated 90° clockwise about the point N to form figure B.
B.
Figure A was rotated 90° counterclockwise about the point N to form figure B.
C.
Figure A was reflected across line m to form figure B.
D.
Figure A was translated 4 units down to form figure B.

B. Figure A was rotated 90° counterclockwise about the point N to form figure B.

To determine which transformation was applied to figure A to form figure B, we can analyze the changes in their positions and orientations.

Looking at the options:
A. Rotation 90° clockwise: This would result in figure A facing downwards, not matching figure B.
B. Rotation 90° counterclockwise: This would result in figure A facing upwards, not matching figure B.
C. Reflection across line m: This could potentially match the change in position and orientation observed in figure B.
D. Translation 4 units down: This would shift figure A vertically downwards, but the orientation would remain the same.

Based on the analysis, the correct answer is option C: Figure A was reflected across line m to form figure B.
