Select the correct mirror image of the given figure when the mirror is placed at MN as shown below.

To find the correct mirror image of the given string E y h 2 b 7 s when the mirror is placed vertically on the right at line MN, we follow the fundamental rules of vertical reflection:

1. Reversal of Sequence: The element closest to the mirror (on the far right, which is 's') will appear first (far left) in the mirror image. The element farthest from the mirror (on the far left, which is 'E') will appear last (far right) in the mirror image.

2. Lateral Inversion of Individual Characters: Each individual character is flipped horizontally from left to right while maintaining its vertical orientation (top remains top, bottom remains bottom):

- s laterally flips to mirror image of 's'.
- 7 laterally flips so its horizontal top bar points left.
- b laterally flips to become d.
- 2 laterally flips to mirror image of '2'.
- h laterally flips to mirror image of 'h'.
- y laterally flips to mirror image of 'y'.
- E laterally flips to mirror image of 'E' (resembling 3).

Analyzing the options based on these transformations:

- Option 1 correctly reverses the entire character order starting with the mirrored 's' and ending with the mirrored 'E', with 'b' correctly converted to 'd'.
- Therefore, the correct option representing the mirror image is the first option.
