Concept:The human eye and a camera function similarly, with comparable parts controlling light entry and image formation.
Explanation:The retina is the light-sensitive layer where the image forms.
In a camera, the film (or digital sensor) serves the same role.
So, Retina corresponds to Film.
The pupil is the opening that allows light into the eye.
In a camera, the aperture is the adjustable opening that controls light entry.
So, Pupil corresponds to Aperture.
The iris controls the size of the pupil.
In a camera, the diaphragm controls the size of the aperture.
So, Iris corresponds to Diaphragm.
Therefore, the correct order is Film, Aperture, Diaphragm.
Answer:D. Film, Aperture, Diaphragm
