Hint: Most of the time cataracts develop by aging or by when there are changes to the tissue via any injury. Some of the diseases that can cause cataracts include diabetes, hypothyroidism, certain genetic illnesses.

Complete answer:
The cataracts are most commonly due to aging but may also occur due to trauma or radiation exposure. It may be present from birth or maybe from the eye surgery for other problems. The risk factors include diseases like diabetes, long-standing use of corticosteroid medication, smoking tobacco, prolonged exposure to sunlight, and alcohol. The underlying mechanism involves the accumulation of clumps of protein or the yellow-brown pigment in the lens that reduces transmission of light to the retina at the back of the eye.
Therefore, the correct answer is Option (C).

Additional information:
The prevention of this includes wearing sunglasses, a wide-brimmed hat, eating leafy vegetables and fruits, and mainly to avoid smoking. The early symptoms may be improved with glasses. If this does not help, the surgery to remove the cloudy lens and to replace it with an artificial lens is the only effective treatment. Cataract surgery is not readily available in many countries, and this surgery is needed only if the cataracts are causing problems and generally results in an improved quality of life.

Note: The cataracts become more common with the age. Additionally, they are more common in women, and less common in Hispanic and in Black people. Surgery is the only way to cure cataract disease.
