• A. Carbohydrate
• B. Protein
• C. Fat
• D. All the above

Answer 1

The correct option is C Fat

Ketone bodies are byproducts in the metabolism of fat. During starvation or fasting conditions the liver synthesizes glucose through a process called gluconeogenesis. Gluconeogenesis is a metabolic pathway that results in the generation of glucose from fat. During gluconeogenesis, the ketone bodies are formed as byproducts where the product is glucose.

So, the correct answer is 'Fat'.
