The image of an object formed by a plane mirror is

Your answer: —  Â·  Correct: B
Explanation

The image formed by a plane mirror possesses distinct characteristics. It is always virtual, meaning the light rays do not actually converge at the image position but only appear to originate from behind the mirror. The image is erect (upright), maintaining the same vertical orientation as the object [1]. Furthermore, the size of the image is exactly equal to the size of the object, with a magnification of one. While the image is laterally inverted (left and right are swapped), it remains upright and of the same dimensions. Unlike concave mirrors, which can produce real or inverted images depending on object distance, a plane mirror consistently produces a virtual, erect, and same-sized image regardless of the object's position [1].
