(D) When a light source is at a very large distance from the observer,the radius of curvature of the wavefront becomes extremely large.As the distance $r 	o \infty$,the curvature $1/r 	o 0$.Consequently,a small portion of a spherical or cylindrical wavefront appears to be flat or planar.Therefore,the wavefront of a distant source is approximately a plane wavefront.

The wavefront of a distant source of unknown shape is approximately
