Why is it useful for more blood to go towards muscles when adrenaline is secreted?

Answer and explanation

Correct answer: Because muscles need more oxygen and energy for quick action

The governing concept is the adrenaline-mediated emergency, or fight-or-flight, response. Adrenaline increases readiness for rapid movement and redirects blood supply toward skeletal muscles. Greater blood flow delivers more oxygen and glucose and helps remove carbon dioxide and other wastes, supporting quick contraction. Therefore option A is correct. Muscle tissue does not produce light, root growth is unrelated, and adrenaline does not simply switch off thyroxine.
