A student obtained a sharp inverted image of a distant tree on a screen placed in front of the concave mirror. He then removed the screen and tried to look into the mirror. He would now see,

• a very blurred image on the wall opposite to the mirror

• an erect and magnified image of the tree in the mirror

• no image as the screen has been removed

• a highly diminished inverted image of the tree at the focus of the mirror
