3. The method to correct hyperopia is to wear a convex lens with an appropriate focal length. Suppose a hyperopic person, at the maximum accommodation of the eye's lens (with the minimum curvature radius), can clearly see objects at a distance of 1.5 meters. What should be the focal length of the convex lens required for them to clearly see an object at a distance of 15 cm?
(A) 14.0 cm
(B) 13.5 cm
(C) 22.0 cm
(D) 15.0 cm
