B or C could work, depending in the shape
A. a reflection to the right and a reflection over the horizontal line of reflection
B. a translation right and a reflection over the vertical line of reflection C. a translation down and a reflection over the horizontal line of reflection D. a counterclockwise 90° turn and reflection down

Option C (a translation down and a reflection over the horizontal line of reflection) fits this criteria. A translation down would move the figure vertically, and a reflection over the horizontal line of reflection would flip the figure. These two transformations combined would result in an image that is on top of the original figure.
Therefore, the pair of transformations that would produce an image on top of the original is option C: a translation down and a reflection over the horizontal line of reflection.
A. A reflection to the right would flip the figure horizontally, and a reflection over the horizontal line of reflection would flip the figure vertically. These two transformations combined would rotate the figure 180 degrees. However, it would not place the image on top of the original figure.
B. A translation to the right would shift the figure horizontally, and a reflection over the vertical line of reflection would flip the figure horizontally. These two transformations combined would move the figure horizontally and reverse its direction. However, it would not place the image on top of the original figure.
C. A translation downward would shift the figure vertically, and a reflection over the horizontal line of reflection would flip the figure vertically. These two transformations combined would move the figure vertically and reverse its direction. This combination would not place the image on top of the original figure.
D. A counterclockwise 90° turn would rotate the figure 90 degrees counterclockwise, and a reflection down would flip the figure vertically. These two transformations combined would rotate the figure 90 degrees counterclockwise and flip it vertically. This combination would place the image on top of the original figure.
Therefore, the correct pair of transformations to place the image on top of the original figure is option D: a counterclockwise 90° turn and reflection down.
