The correct answer is A; because of diminishing sensitivity to contrasts and reduced tolerance for glare.
Further Explanation:
As people age, the eyes do not work as they did when they were younger. The glare from headlights hurt older people's eyes and can cause accidents since they can't see temporarily. This causes the person driving to swerve, drive slower, and could cause a wreck.
There also may be a problem with the dark roads if their headlights are not bright enough and they have to drive with their lights on high and this will cause an issue for oncoming drivers.
