A convex mirror always ___________ ?

A. Forms a real image
B. Forms a virtual image 
C. Forms an inverted image
D. Produces a larger image

In convex mirrors light rays from a point always gets diverged (they dont meet at any point). So we have to extend them behind the mirror so that they appear to meet. Since image is formed behind of mirror, they cant be received on screen. So it is not real image. Thus it is a virtual image.
