To find the mirror image of a given figure when a mirror is placed on the shaded line, follow these steps:

1. Understand that the mirror image inverts the original figure along the axis where the mirror is placed. In this case, the inversion occurs along the vertical line.
2. The left side of the figure becomes the right side in the mirror image, and vice versa.
3. Look at the structure of each digit and each part of the figure. Each digit will appear reversed in the mirror image.
4. Identify the key elements of the original figure that will have distinctive mirror inversions (e.g., the digit '6' will appear like a reversed '6').

After observing the options provided, compare each one with the expected mirror image characteristics.

In the correct option, you can see that:

• The number '64ad' has its digit '6' mirrored on the left side.
• The numbers have reversed order and appearance correctly as per mirror reflection.

Thus, the correct option that represents the mirror image of the given figure is the last one provided.
