Plane mirrors don't usually form real images.
They form "virtual images" of real objects.
However, things can be arranged so that a plane mirror does form a real image.
A convergent light beam can do this.
So the answer is "convergent".
You should be able to show this by drawing a "ray diagram" for the light beam. The reflected rays converge and that's what's needed to produce a real image.
A "real object" always produces a "virtual image" in a plane mirror. That's because the reflected rays diverge.
Interestingly, a plane mirror can form a real image if the object itself is virtual.
Hope this helps you

A real image is formed only when light rays converges after reflection from a mirror. So, the pencil of light incident
on the mirror must be convergent, so that after reflection they meet at a point.
