Detailed Solution

The above statement is true.
The image of the football can be seen on the ground because the football is close to the ground, so the ground will act as a screen, and the image will be formed on the ground. Still, when the football is high in the sky, it is far from the ground. The football cannot make the image on the ground due to the distance. Therefore, we cannot see the image of football when it is high in the sky.
