To solve this problem, we need to determine which option correctly represents the reflection of the given figure with respect to the dotted line (mirror line).

Reflection in a mirror involves flipping the object over the line of reflection. The properties of such reflections are:

• Each point of the original figure and its image will be equidistant from the mirror line.
• The shape and size of the object remain unchanged, but the orientation is reversed.
• The left and right sides are flipped, similar to how text appears backward in a mirror.

Let's analyze the given figure, which consists of a complex shape. To find the correct reflection:

1. Identify the distances of key points of the figure from the mirror line.
2. Ensure that these points retain their distances but switch sides relative to the mirror line.
3. Check that the orientation of shaded and non-shaded areas is flipped correctly.

Given the options and the correct answer image:

This option shows the figure correctly reflected across the mirror line:

• The distances between corresponding points on the figure and its image are equal on either side of the dotted line.
• The orientation of the shaded segments is appropriately flipped, matching the reflection property.

Conclusion: The correct reflection is represented by the image provided, which accurately mirrors the given figure across the dotted line. Therefore, this is the correct choice.
