(b) Eyes lens losing flexibility resulting in a kind of long-sightedness in elderly people.

Answer 1

Presbyopia:

1. It occurs in people who are 40-50 years of age
2. This defect occurs due to the hardening of the lens as a part of aging.
3. As the lens loses its flexibility, its ability to change the focal length to focus on nearby objects is lost.
4. So elderly people with presbyopia experience long-sightedness.

Final answer: Eyes lens losing flexibility results in a kind of long-sightedness in elderly people due to Presbyopia.
