In a plane mirror, an object is 25 cm in front of the mirror. Where is its image?

Explanation:
In a plane mirror, the image forms at a distance behind the mirror equal to the object’s distance in front of the mirror. This happens because the reflected rays appear to originate from a point behind the surface when extended backward, giving a virtual image. Since the object is 25 cm in front, the image sits 25 cm behind the mirror along the same line. So the image location is 25 cm behind the mirror. It’s a virtual, upright image, and cannot be projected onto a screen. The other options don’t fit because a plane-mirror image can’t lie in front of the mirror or off to the side, and the distance behind the mirror equals the object distance, not a different value.
