Solution
The correct option is D Principle of reversibility
The principle of reversibility of light :-
Path of ray of light is reversible or light traces back it's path while travelling in reverse direction or a ray of light can pass in either direction along the same path
Note the directions of the arrow.
The
beam of light travels back on the same path as it was traveling before
the refraction and after the refraction after being encountered by the
obstacle in the water.
