Select the correct mirror picture of the given figure when the mirror is…

Analyze the Transformation: To reach Option 4, the image "u P 2 3 A B" undergoes both a sequence reversal and a vertical flip (180-degree rotation).

Apply Logic: When the mirror at MN is treated as a pivot for both vertical and horizontal flipping, the characters are inverted both ways.

Final Result: The sequence becomes inverted and reversed, resulting in the arrangement shown in Option 4.
