In FEM, which option is the most realistic representation of the actual force between deformable bodies?

(c) Sine distribution

I got this question in examination.

Right option is (c) Sine distribution

To explain I would say: A situation where the representation of boundary forces is subject to different interpretations is found when the force is due to contact between two bodies. For example, a solid plate in contact with a circular disc generates a reactive force that can be represented either as a point load or as a locally distributed force. A sine distribution might be a more realistic representation of the actual force between deformable bodies.
