The colours seen in a soap bubble arise from interference of light reflecting off the front & back surfaces of the thin soap film. Depending on thickness of film, different colours interfere constructively & destructively. As the position of eyes is changed, path difference corresponding to different wavelength of the light emitted by the bubble change. Thus the intensities of different wavelengths are different resulting the bubble to be appeared colored. Option −D is correct.

Explanation:
Interference of light is the reason why bubbles of colorless soap solution appear colored in sunlight. This phenomenon occurs due to the interference of light waves that are reflected from the front and back surfaces of the soap bubble.
When light waves pass through the soap solution, they are refracted and reflected at the front and back surfaces of the bubble. The difference in the path lengths of the reflected waves causes them to interfere with each other.
The interference of the light waves produces a series of bright and dark fringes, which are observed as a colorful pattern on the surface of the bubble. The colors seen are due to the constructive and destructive interference of the light waves.
The colors seen on the soap bubble depend on the thickness of the soap film. Thicker films produce brighter colors while thinner films produce duller colors. When the thickness of the soap film is such that the path lengths of the reflected waves differ by an integer multiple of the wavelength of light, the waves are said to be in phase and produce a bright fringe.
On the other hand, when the path lengths differ by an odd multiple of half the wavelength of light, the waves are said to be out of phase and produce a dark fringe. This is how the colorful pattern is produced on the surface of the soap bubble.
Conclusion:
In conclusion, the reason why bubbles of colorless soap solution appear colored in sunlight is due to the interference of light waves that are reflected from the front and back surfaces of the soap bubble. This phenomenon is a result of the interaction between the soap solution and the light waves and is a fascinating example of the properties of light.
