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

To find the correct mirror image of the given string 5Fm39d when the mirror is placed vertically at MN on the right side, we reflect each character laterally (left-to-right swap):

1. The rightmost character in the original image is d, so its mirror image will appear first (on the far left). The lateral reflection of 'd' is b.

2. The second character from the right is 9, whose mirror image is ρ (or reversed 9).

3. The third character from the right is 3, whose mirror image is ε (or reversed 3).

4. The fourth character from the right is m, whose mirror image remains m.

5. The fifth character from the right is F, whose mirror image is a laterally inverted F („ / reversed F).

6. The leftmost character is 5, which appears on the far right as a mirrored 5 (ƀ / reversed 5).

Combining these horizontally flipped characters gives the exact combination shown in Option 1:


Therefore, the correct choice is Option 1.
