Solution

The correct option is C A condition, in old age, in which eyesight becomes foggy

Sometimes, particularly in old age, eyesight becomes foggy. It is due to the eye lens becoming cloudy. When this happens, a person is said to have cataract. It is possible to treat this defect. The opaque lens is removed and a new artificial lens is inserted. Modern technology has made this procedure much simpler and safer.
