Option C: Behind the retina
In hypermetropia (far-sightedness), the eyeball is too short, so the image of a nearby object is focused behind the retina instead of on it. It is corrected using a convex lens.
The "What you have learnt" section of Chapter 10 directly states: "Hypermetropia (far-sightedness – the image of nearby objects is focussed beyond the retina)." "Beyond the retina" and "behind the retina" mean the same thing here. Examiners expect you to recall this one-line definition precisely. Myopia is "in front of" the retina; hypermetropia is "behind" — keep these two contrasted clearly.
