    Option C, Ketone body synthesis

    Explanation:

    Ketone bodies are used as a source of energy when glucose is not easily available as energy source. This usually happens when a person is fasting and hence does not intake any glucose. There are three main ketone bodies a) acetoacetate, b) 3-beta-hydroxybutyrate and c) acetone. When our body do not receive food for a long time or a person undergo rigorous and continuous physical exercise, then the level of ketone bodies increases in the blood

    Hence, option C is correct
