Solution

The correct option is C is a geometrical method to find a wavefront
Huygen's principle: Every point on a wave-front may be considered a source of secondary spherical wavelets which spread out in the forward direction at the speed of light. The new wave-front is the tangential surface to all of these secondary wavelets.
