Solution
The correct option is D The edge of a table
In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point.
Sun rays in space have the Sun as their starting points, and the rays of light continue indefinitely.
A person hitting a tennis ball could cause it to travel as a ray if there were no resistance from the air.
Rays coming from a torch light have the torch as their starting points, and the light rays continue indefinitely.
The edge of a table will have two end points. So, it is not a ray.
Therefore, option 'd' is correct.
