General KnowledgeBiology
- A1 only
- B2 only
- C1 and 3
- D2 and 3
Explanation
Presbyopia is the age-related loss of the eye lens's ability to accommodate, so near vision blurs — it usually develops with ageing. It is corrected with bifocal lenses (combining concave and convex segments) or progressive lenses. Inability to distinguish colours is colour blindness, a different defect unrelated to presbyopia. Statements 2 and 3 are correct while statement 1 is false. Hence option D is correct.
