To solve this question, we need to determine the mirror image of the given figure when a mirror is placed on the shaded line.

When creating a mirror image, the orientation of the objects relative to the mirror line is reversed while maintaining the relative positions of the parts of the figure.

Let's analyze the given figure:

Now, compare each of the options provided to find which one correctly represents the mirror image of the original figure:

1. 

   This option does not accurately reflect the orientation reversal across the mirror line.

2. 

   This option accurately reflects the orientation with respect to the mirror line. Hence, this is the correct mirror image.

3. 

   This option shows inconsistencies with the orientation and relative positions after reflection.

4. 

   This does not appropriately reflect the figure across the mirror line.

Thus, the correct mirror image is represented by the second option:
