Understanding Genetic Disorders

A genetic disorder is a health condition caused by abnormalities in genes or chromosomes. These disorders can be inherited or caused by mutations that occur during a person's life.

Analyzing the Options

1. Kwashiorkor - This is a form of severe malnutrition caused by a lack of protein in the diet. It is not genetic.
2. Marasmus - This is another type of malnutrition resulting from a deficiency of caloric intake. Like Kwashiorkor, it is not a genetic disorder.
3. Phenylketonuria (PKU) - This is a genetic disorder caused by a deficiency of the enzyme phenylalanine hydroxylase, leading to an accumulation of phenylalanine in the body, which can cause intellectual disability.
4. AIDS - Acquired Immunodeficiency Syndrome is caused by the human immunodeficiency virus (HIV) and is not a genetic disorder.

Final Answer

The correct answer is C. Phenylketonuria (PKU) as it is the only option that represents a genetic disorder.
