Convex mirror
Explanation:
Magnification is the ratio of the height of the image to the height of the object.
It is given that the magnification of a mirror is always less than 1. The mirror must be a spherical mirror as the magnification of a plane mirror is always 1, not less than that.
In a concave mirror, magnification is equal to the negative of the ratio of the distance of the image from the mirror to the distance of the object from the mirror.
So the given mirror must be a convex mirror as it always produces images smaller than the size of the object and its magnification is always less than 1.
