The correct answer is  Ans. C: Age related Age-related/senile cataract is the most common cause of catarcat. It may be of significance that as age progresses the semipermeability of the capsule is impaired, the inactive insoluble proteins increase, and the antioxidative mechanisms becomes less effective.
