No matter how far you stand from a spherical mirror, your image appears erect. The mirror may be a plane or convex mirror.

Explanation

The image formed by a plane mirror is virtual, erect (upright), of the same size as the object, at the same distance behind the mirror, and laterally inverted.

Convex mirror refers to the mirror that is curved outward in the middle and, whose reflecting surface is away from the center of curvature. It forms a virtual, erect (upright) and diminished image behind the mirror.

So, option (d) is correct.
