To solve this problem, we need to determine the mirror image of the given figure when the mirror is placed at line MN. The concept of mirror images involves reversing the position of elements with respect to the mirror line.

The given figure consists of the sequence "kj09wn2fx", and the mirror is vertically placed at the right (MN line).

Let's consider the rules for finding the mirror image:

• The mirror image of a letter or number reverses horizontally. For example, if 'a' faces right, its mirror image will face left.

Following these rules, if we reverse the sequence "kj09wn2fx" horizontally, it will appear as follows:

• The first position in the mirror image will be occupied by 'x'.
• The second position by 'f'.
• Following that, it continues with '2', 'n', 'w', '9', '0', 'j', and finally 'k'.

Thus, the correct mirror image is "xf2nw90jk". Comparing this with the options provided, we identify the correct answer as follows:

This option displays "xf2nw90jk", which matches our sequence perfectly.
