Feeling the tremors of an earthquake a scared resident of the seventh floor of a multistoried building starts climbing down the stairs rapidly. Which hormone initiated this action?

Explanation

The correct answer is Adrenaline. This hormone is crucial during stressful situations, such as feeling the tremors of an earthquake, as it prepares the body for rapid physical action, which is essential for survival. Adrenaline enhances heart rate, increases blood flow to muscles, and facilitates quicker responses, which would enable a resident to climb down stairs rapidly.In contrast, Glucagon, Gastrin, and Thyroxine do not have immediate effects on the physical responses associated with stress. Glucagon is primarily involved in blood sugar regulation, Gastrin aids in digestion, and Thyroxine controls metabolic rate, making them irrelevant to the scenario described in the question.
