Which of the following best defines normal respiration rate?

Explanation:
Normal respiration rate in a healthy adult at rest is about 12 to 20 breaths per minute. This range reflects a balanced ventilatory drive that meets metabolic needs without effort or distress. Measurements should be taken when the person is calm and at rest, counting for a full minute to be accurate. Rates below this range can indicate bradypnea from factors like medications or neurological issues, while rates above this range—20 to 28 or higher—suggest tachypnea and can occur with fever, infection, hypoxia, acidosis, anxiety, or pulmonary disease. Therefore, 12–20 breaths per minute is the best definition of normal resting respiration rate.
