Solution

The correct option is C Proteins
Phenylketonuria (PKU) is an inborn metabolic error with impaired metabolism of phenylalanine causing its increased blood level. A person with phenylketonuria has a defective gene for phenylalanine hydroxylase. The enzyme breaks down an essential amino acid called phenylalanine. Being essential amino acid, it is present in proteins and therefore, protein diets should be avoided by Rishi suffering from phenylketonuria. Thus, the correct answer is option C.
