Solution
The correct option is D Rectilinear propagation of light
In the setup, when the orifices A, B and C lie along a straight line, the observer is able to see the candle. If the position of any of the orifices or the candle is shifted, the observer no longer would be able to see the light source. This demonstrates that light travels in straight lines. This property is also known as rectilinear propagation of light.
