Plane mirrors always produce upright, virtual images. In D, the object is located beyond the center of curvature of a concave mirror. At such an object location, the image would be real, inverted and reduced in size. In E, the object is located in front of the focal point of a concave mirror. At such an object location, the image would be virtual, upright , and magnified.
Virtual images formed by mirrors are always upright images.
A This is a true statement. The image characteristics of being upright and being virtual go hand in hand. Only real images are inverted and only inverted images are real.
