Solution
The correct option is C As light travels in a straight line, light from the top of the object after passing through the pinhole will reach the bottom of the camera screen and light from the bottom of the object will pass through the pinhole and reach the top of the screen. So, a pinhole camera always produces an inverted (upside down) image.
