Solution
The correct options are
C
D
In a pinhole camera, for the image to be as same as that of the object, the object should have both horizontal and vertical lines of symmetry. Amongst the given options, only the hexagon and the ellipse have the desired symmetry. Hence their images would look the same as the object.
