What is the shape of the wavefront on earth for sunlight?

Option A

Option B

Option C

Option D

Solution

As shown in the figure, when a wavefront emitted from Sun reaches Earth at a very long distance it seems to be almost planar when observed locally in a finite region. Hence they become plane wavefronts.
