Answer 1

The correct option is D Phenylalanine

Phenylketonuria (commonly known as PKU) is an autosomal recessive metabolic genetic disorder disorder that increases the levels of a substance called phenylalanine in the blood. Phenylalanine is a building block of proteins (an amino acid) that is obtained through the diet. Phenylketonuria is characterized by a mutation in the gene for the hepatic enzyme phenylalanine hydroxylase (PAH). The disease may present clinically with seizures, albinism (excessively fair hair and skin).

So, the correct answer is 'Phenylalanine'.
