Concept:A plane mirror always forms a virtual image that is erect and of the same size as the object.
Explanation:The image formed by a plane mirror has these characteristics:
It is virtual, so it cannot be obtained on a screen.
It is erect or upright, not inverted.
It is the same size as the object, so it is neither magnified nor diminished.
It is laterally inverted, meaning left and right appear swapped.
The image distance from the mirror equals the object distance from the mirror.
These properties show that the image is not real, magnified, or inverted.
Therefore, the correct option is the one that describes the image as virtual.
Answer:D. virtual.
