Examples of mirror and water reflections are shown in the figures below: An object appears as the following image after first reflecting in a mirror and then reflecting on water. The original object is
To solve this problem, we need to understand the transformation caused by mirror and water reflections on an object's image.
First, observe the given transformations: The image of the object is first reflected in a mirror (which provides a lateral inversion), followed by a water reflection (which provides a vertical inversion).
Examine the final reflected image:
The final image implies that the left and right sides of the object have been swapped due to the mirror, and then flipped upside down due to the water reflection.
Determine the original object: We need to find an object that, when transformed by mirror reflection and then water reflection, results in the given final image.
We'll examine the options:
This object, when mirrored, will swap sides. The subsequent water reflection will flip it upside down, matching the given final image. Hence, this is the correct original object.
When mirrored and then vertically flipped, it does not match the final image.
This does not match after transformations.
Post transformations, does not match the final image either.
The only option that matches the transformations of mirror and water reflections is the first one:

A line of symmetry is defined as a line that divides a figure into two parts in a way such that each part is a mirror image of the other part about that line.
