To find the water image of a word or diagram, we must understand how a reflection in water works. In water images, the reflection is vertical, meaning the top of the object appears at the bottom and vice versa, similar to how it would appear on a water surface.

Let's analyze the options given for the word "WATER-IMAGE":

1. Observe the given image options and identify the water image characteristics:
   • Each letter should appear upside down as if rotating over the x-axis.
   • The sequence of letters remains unchanged.
2. Analyze each option:
   • Option (a): The letters are not correctly inverted vertically, so it cannot be the correct water image.
   • Option (b): Similar issue as above; letters are incorrectly flipped, not matching the water image characteristics.
   • Option (c): The letters are upright, not upside down, hence incorrect.
   • Option (d): The letters appear correctly upside down, matching the characteristics of a water image.
3. Conclusion: After examining all options, Option (d) is the correct water image of "WATER-IMAGE."

Therefore, the answer is Option (d).
