Answer: D - Hyperventilation.
Explanation: Hyperventilation is breathing in excess or overbreathing more than what the body needs.
Fast and deep breathing occurs when one's rate of breathing removes more carbon dioxide than the body can produce. This can change what is in the blood due to the reduction in the concentration of carbon dioxide dissolved in the blood which can cause the blood pH to rise, leading to respiratory alkalosis.
Some conditions which can bring about hyperventilation include Anxiety disorder, Panicattack, Asthma,Stress, effect of drugs, head injury etc.
