Answer 1

Answer:

(b). an erect and magnified image of the tree in the mirror

Answer 2

(D) a highly diminished inverted image of the tree at the focus of the mirror.

The student obtained a sharp inverted image of a distant tree on a screen placed in front of the concave mirror. So the light rays from infinity where reflected by the concave mirror and an image was formed the focus, as per the properties of the mirror. Now, if the student removed the screen and tried to view the image with his eyes. He has replaced the screen with the human eye. There is no change in the property of the mirror. The image would still be inverted and diminished, but formed on the human retina instead of the screen.
