B Correct answer
Explanation

Hypermetropia (farsightedness) occurs when the eye is too weak or too short, focusing images behind the retina. A convex (converging) lens adds focusing power to bring images forward onto the retina. Concave lenses are for myopia, while plano-convex and plano-concave describe lens shapes, not the complete solution.
