To solve this problem, we need to find the mirror image of the given figure when the mirror is placed at line MN. The mirror image will be a reversed version of the original figure as if it is reflected in a mirror placed vertically at MN.

Step-by-step Solution:

1. Identify the figure given in the question, which contains text and numbers: GRO36VEt.
2. When creating a mirror image along a vertical line (MN), the order of elements (including text and numbers) will reverse horizontally.
3. Each character will remain the same, but the sequence will reverse. Hence, the mirror image will read from right to left.
4. The transformation results in the mirrored sequence: tEV63ORG.

Now, let's use the options provided to identify the correct mirror image:

Correct Mirror Image:

This option correctly reflects the original sequence in reverse order, consistent with the placement of the mirror at MN.

Conclusion: The correct mirror image is the option where the text "GRO36VEt" is read as "tEV63ORG". This matches the provided correct answer and will help in identifying mirror images in similar reasoning questions.
