Greetings, The Myschool Team.
The correct answer is A(lens and the film) and not B(diaphragm and the shutter).
Here are a few references:
"There is a provision for adjusting the distance between the lens and the film..."
Source: Application of Light Waves, Chapter 14(Book II), New School Physics
Thus, the correct answer is A(lens and the film) and not B(diaphragm and the shutter).

This adjustable distance is crucial for focusing the image onto the film (or sensor in digital cameras). By changing the distance between the lens and the film, the camera can adjust the focal length and achieve sharp focus on the subject.
Therefore, the correct answer is A. lens and the film.
