Open in App
Solution
The correct option is A X
As the parallel rays from infinity are focussed by the eye lens on the retina of the normal eye, the maximum focal length of the eye lens will be equal to the distance between the retina and the eye lens, i.e., equal to X.
Hence, the correct answer is option (a).
