Hint: Human eye is an important sense organ that helps to provide vision to all the living organisms. The image from the human eye is sent to the brain cerebrum for the processing. In the same way a camera is an artificial eye or a mechanical eye, that takes an image.

Complete answer:
Diaphragm is present in the camera which is used to control the light that gets into it. Where in the eyes the iris is used for this purpose. The lens is used to focus the object and the image formed is real and inverted. In the eyes the image focused by the lens falls on the retina and this image is converted in the image processing system of rod and cone cells into the electrical impulse and it sends to the optical nerve of the brain. In the case of the camera, the film is used to record the image taken.
The shutter in the camera is similar to that of the eyelids over the eye. This is because both help in protecting the lens. The outer box of the camera and the sclerotic layer of the eyes are similar. The sclerotic layer is the outermost layer of the eye. Inside of this layer, the choroid layer is present which is similar to that of the black inner paint of the outer box of the camera. The pupil helps in controlling the light entering through them into the eye, it is what the light hole in the camera does. The image formed by both camera and the retina are small and inverted in nature.

Thus the correct answer is option ‘A’.

Note: Human eyes and camera are moreover similar to each other. Both focus the inverted image of the object. In camera, it focuses on the screen of the camera by the aperture control where in the eye it is focused on the retina with the rod and the cone cells of the iris.
