A virtual image is a copy of an object formed at the location from which the light rays appear to come. Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object.

Understanding Plane Mirrors
A plane mirror is a flat reflective surface that produces images through the reflection of light. Let's explore why option 'C' is the correct statement regarding plane mirrors.
Image Characteristics
- Virtual Image: The image formed by a plane mirror cannot be projected onto a screen, as it appears to be behind the mirror. This type of image is called virtual.
- Erect Image: The image retains the same orientation as the object. For instance, if you raise your right hand, the image in the mirror raises its right hand as well.
- Laterally Inverted: The image is reversed from left to right. This means that a person facing a mirror will see their left side appearing as the right side in the reflection.
Why Other Options Are Incorrect
- Option A: "Its focal length is zero."
- This is misleading; a plane mirror does not have a focal point since it reflects parallel rays back parallel, making its focal length effectively infinite.
- Option B: "The size of the image of an object placed in front of the mirror is slightly less than that of the object."
- This is incorrect. The size of the image in a plane mirror is equal to the size of the object.
- Option D: "Its focal length is 200 cm."
- This is also incorrect, as plane mirrors do not have a measurable focal length like concave or convex mirrors.
Conclusion
In summary, option 'C' accurately describes the properties of the image formed by a plane mirror. The image is virtual, erect, and laterally inverted, making it the correct choice among the options provided.
