Solution

The correct option is D (A)-2, (B)-1, (C)-4, (D)-3
A plane mirror forms a virtual and erect image. The size of an image is the same as the size of the object.
A convex mirror always forms a virtual, erect and diminished image.
A convex lens can form enlarged images and thus are used in magnifying glass and microscope.
Dentists use a concave mirror to see an enlarged image of the teeth. If an object is placed close to a concave mirror it a forms an erect and enlarged image of the object.
