Huygens' principle states that every point on a wavefront can be considered as a source of new waves, which propagate out in all directions at the same speed as the original wave. This principle helps explain phenomena such as diffraction and interference. Option A is not correct as only edges of an obstruction (or any disturbance in the path of a wave) act as diffraction sources. Option C is not correct as the superposition of every other part of the wave leads to interference and not Huygens' principle. Option D is not incorrect, but option B is the most appropriate answer.
