To solve the problem of finding the mirror image of the given figure, we need to understand how reflections work. A mirror image is a flipped version of the original image as if viewed in a mirror placed along the specified line. Here are the steps to determine the correct mirror image:

1. Identify the axis where the mirror is placed. In the given image, the mirror is aligned along the right side.
2. Observe the original image carefully. Notice the orientation and position of each element (letters and lines).
3. For each element, flip it horizontally with respect to the mirror line. This will reverse the order of elements, but each element's top and bottom remain unchanged.
4. Compare the flipped image with the given options to find the correct mirror image.

By following these steps, we can determine that the correct mirror image is as follows:

This option displays the mirrored letters and orientation accurately as per the original image's reflection along the shaded line.
