To find the mirror image of a figure, we need to understand that the image will be flipped along the axis where the mirror is placed. In this question, the mirror is placed on the vertical line next to the given figure.

Step-by-step Explanation:

1. Analyze the original figure and note the orientation of each component (letters and numbers).
2. Visualize how each element would appear if flipped horizontally across the line where the mirror is placed.
3. Compare each option provided to determine which one matches the expected mirror image based on the above step.

The correct mirror image will have all characters flipped horizontally.

Conclusion:

After examining the options, the first option is the correct mirror image of the original figure. Here it is displayed for clarity:

Thus, the answer is the first option where all the elements are flipped accurately according to the mirror's placement.
