To determine the correct mirror image of the given figure when the mirror MN is placed to the right side, we need to understand the concept of mirror images. A mirror image is a flipped version of a figure, much like a reflection seen in a mirror. Each element on the right of the original figure will appear on the left in the mirror image, and vice versa.

Let's analyze the components:

• The given figure consists of a shape with a specific orientation.
• In mirror images, horizontal positions are reversed; elements on the right move to the left.

Let's observe the options provided and determine the correct mirror image:

By closely examining the images, the fourth option is the correct mirror image of the given figure when the mirror is placed to the right. The shapes align correctly as they would appear in a mirror reflection.

Therefore, the correct answer is:
