Solution
The correct option is A Adrenaline Adrenaline is a hormone secreted by the adrenal medulla during very stressful situations. This hormone is also called the emergency hormone because it makes the individual think and respond quickly to the situation. The hormone increases the heart rate, dilates the pupils and increases the blood glucose level.
