The correct answer is: D
Explanation
Inbreeding is the mating of organisms that are more closely related than would normally occur in nature. This can include mating between siblings, parents and children, or first cousins. Studies have confirmed an increase in several genetic disorders due to inbreeding such as blindness, hearing loss, neonatal diabetes, limb malformations, disorders of sex development, schizophrenia and several others. In adults, inbreeding can lead to deafness, visual impairment, and mental deficiency.
