Options
A A converging lens.
Correct Answer
B A diverging lens.
C A cylindrical lens.
D A prism lens.
Correct Answer

Option A is the correct answer.

Detailed Explanation

The text states, "To correct this defect [presbyopic or hyperopic], a converging lens is used to focus the image on the retina..."

Hint

Hyperopia/presbyopia causes light to focus too late (behind the retina); a lens is needed to bring the light rays together sooner.
