Final answer:
A malignant tumor of the eye that is known to be hereditary is Retinoblastoma (A), caused by a mutation in the RB1 gene.
Step-by-step explanation:
The type of malignant tumor of the eye known to be hereditary is Retinoblastoma (A). Retinoblastoma is a cancer that quickly develops from the immature cells of a retina, the light-detecting tissue of the eye. It is most commonly found in young children and can be hereditary, which means it is passed down from parents to their children. This condition is due to a mutation in the RB1 gene, which plays a crucial role in the suppression of tumors by controlling cell division. If the gene is mutated, it fails to control cell growth, leading to the formation of a tumor within the eye.
The malignant tumor of the eye that is known to be hereditary is Retinoblastoma. Retinoblastoma is a rare type of eye cancer that begins in the retina, the sensitive lining on the inside of the eye.
