Final answer:
An albino individual cannot produce melanin, which is responsible for pigmentation in skin, hair, and eyes. The option (D) is correct.
Step-by-step explanation:
An albino individual cannot produce melanin. Melanin is a pigment responsible for the color of the skin, hair, and eyes. In humans, albinism is a genetic disorder characterized by a deficiency of the enzyme tyrosinase, which is necessary for the production of melanin in melanocytes.
Because of this deficiency, individuals with albinism present with very pale skin, light-colored hair, and vision problems due to the absence of pigmentation in the retina. Melanin also plays a role in protecting the skin from UV damage, making those with albinism more susceptible to sunburns and skin cancer. Therefore, treatments often include measures to protect the skin and eyes from UV light exposure. Therefore, option (D) is correct.
