To solve the problem of determining the mirror image of Figure X, we need to analyze what happens to an image when it is mirrored. A mirror image is a reflection where left and right are reversed.

Let's analyze the clock in Figure X. Observe the positions of the hour and minute hands:

• The hour hand is pointing slightly above the horizontal position towards the right.
• The minute hand is pointing towards a lower-left position.

In a mirror image:

• The hour hand will point towards the left horizontally.
• The minute hand will point towards a lower-right position.

Now, let's review the options:

• Option A: Both hands do not mirror the positions correctly.
• Option B: Also does not align with the mirror image correctly.
• Option C: Shows incorrect mirroring for both hands.
• Option D: The hour and minute hands are correctly mirrored: the hour hand points left horizontally and the minute hand points lower-right. This correctly represents the mirror image of Figure X.

Therefore, the correct mirror image is in Option D.
