• C. It forms a real, inverted, and magnified image.
• D. It forms a virtual, erect, and magnified image.

Answer 1

The correct option is B It forms a virtual, erect, and diminished image.

A convex mirror always forms a diminished, virtual, and erect image. Also, it allows more light to fall because of the nature of its curvature as it has more field of view. Thus, the mirror is used as a rear-view mirror in vehicles.
