Detailed Solution

If the upper half of the mirror is covered, then the brightness of the image will be reduced.
If the concave mirror is covered, the light rays from the object focusing on the mirror are reduced. This results in reducing the brightness of the image. In addition, there would be no change in the object's size because its distance is not changed. This is because covering the upper half of the mirror has no effect on the position of the image formed because the focal length and object distance remain constant. It has no effect on the nature or position of the image because the object distance and focal length remain constant.
