The answer to this question is letter A. If you are not familiar with Albinism, this is a type hereditary disorder that is often related to hypopigmentation. One of the most common forms of Albinism is OCA or Oculocutaneous Albinism. This type of albinism occurs because of the autosomal recessive trait which explains why A is the right answer.

Those who have this condition will showcase the signs and symptoms through the appearance of the eyes, the hair follicles, and the skin. Usually, the skin shows a deficiency in melanin. Those who have albino usually have light-colored skin and hair as compared to the rest of their family members who do not have the same traits.
