The correct answer is: D) cortisol.
Cortisol is a steroid hormone released in response to stress and low blood-glucose concentration. So, its function is to increase blood sugar levels and it does that through gluconeogenesis in liver.
Gluconeogenesis is a metabolic process of glucose production from certain non-carbohydrate carbon substrates such as glucogenic amino acids or glycerol.
Gluconeogenesis is a regulation process that maintains homeostasis by avoiding states with low levels of glucose (hypoglycemia).
