B) The inhibition of normal myelin development in the individual's brain
Explanation:
Phenylketonuria is a disorder characterized by abnormal levels of phenylalanine in the body. It is <u>caused by mutation in DNA that leads to the deficiency of an enzyme known as phenylalanine hydroxylase, which converts phenylalanine to tyrosine</u>, a fundamental substance for dopamine production - related to working memory.
