Solution

The correct option is C increases
The following diagrams represent how the size of the image varies as we move the object towards the camera and also away from the camera.

From the above cases, we can conclude that the size of the image formed in the pinhole camera decreases when we move the object away from it and the size of image increases as we move the object towards the camera provided the screen is kept fixed.
