lol.Yeah it is .but among those above,i think A is the correct answer cause tyrosine is an aromatic amino acid.The patient has albinism caused by a deficiency of tyrosine hydroxylase, blocking the production of melanin from tyrosine.Anyway,i m not sure

A friend of mine asked me that question.I chose A cause the other options are not related to albinism at all.But i m pretty sure tyrosine is an aromatic amino acid.I really don t know if we should memorize the aromatic ring structures like that
