Geometry

When a 3D object is represented in 2D space, one of the three dimensions (depth) is lost, leading to distortion. This can affect how angles, proportions, and perspectives appear.

The other options are incorrect:

Option B: It can be a consequence of trying to represent 3D in 2D, but it is not the fundamental reason for distortion. Angle measurements change because of the loss of depth, not the other way around.
