In which situation is increased secretion of adrenaline most expected?

Answer and explanation

Correct answer: On suddenly seeing danger

Adrenaline, also called epinephrine, is released by the adrenal glands during sudden fear, danger, or intense stress. It prepares the body for a rapid emergency response by increasing heart rate, breathing rate, and blood supply to skeletal muscles. Therefore, suddenly seeing danger is the best answer. Peaceful sleep, calm study, and ordinary digestion do not normally cause this strong fight-or-flight response.
