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

The correct answer is Option 2.

Step-by-step explanation:

1. Mirror Position: The mirror MN is placed vertically on the right side of the given letter sequence R k g E y w.

2. Rules of Lateral Inversion:
- Positional Reversal: The sequence of characters reverses horizontally. The rightmost character closest to the mirror line appears first on the left in the mirror image, and the leftmost character appears last on the right.
- Lateral Inversion: Each individual character is flipped horizontally from left to right.

3. Reflected Character Sequence (from Left to Right):
- The rightmost character w becomes the 1st character on the left (remains w).
- The 2nd character from the right y becomes the 2nd character on the left, horizontally flipped.
- The 3rd character E becomes the 3rd character on the left, laterally inverted as Ǝ.
- The 4th character g becomes the 4th character on the left, horizontally flipped.
- The 5th character k becomes the 5th character on the left, laterally inverted as ʞ.
- The leftmost character R becomes the 6th (last) character on the right, laterally inverted as Я.

4. Conclusion: Combining these laterally inverted characters in order gives the sequence: w y Ǝ g ʞ Я.

This corresponds exactly to the figure in Option 2:
