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

The correct answer is:

Step-by-step Explanation:

When a vertical mirror is placed on the right side (at line MN) of the given letter/number sequence MdF37A, the resulting mirror image undergoes two main changes:
1. Reversal of Position (Right-to-Left): The order of the characters is reversed. The character closest to the mirror (on the rightmost side) becomes the first character in the reflection (on the leftmost side). Therefore, the sequence reverses its order from M - d - F - 3 - 7 - A to A - 7 - 3 - F - d - M.
2. Lateral Inversion (Horizontal Flip): Each individual character is flipped horizontally from left to right, while its vertical orientation (top-to-bottom) remains the same.

Let's analyze the lateral inversion of each character in the reversed order:
• A: Since it is vertically symmetrical, its horizontal reflection remains unchanged as A.
• 7: The horizontal top bar points to the right in the original; in the reflection, it points to the left.
• 3: The curved parts open to the left in the original; in the reflection, they open to the right.
• F: The horizontal arms pointing to the right in the original now point to the left in the reflection.
• d: The circular loop on the right side of the vertical stem flips to the left side, appearing like a b.
• M: Since it is vertically symmetrical, its horizontal reflection remains unchanged as M.

Combining these horizontally flipped characters from left to right yields the correct mirror image: A - (flipped 7) - (flipped 3) - (flipped F) - b - M.

Comparing this with the given options, the image that matches this sequence is the one shown in the correct option:
