• 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. Hence, it has more field of view. Thus, a convex mirror is used as a rear-view mirror in vehicles.
