The correct option is C. biofeedback.
Step-by-step explanation:
The gathering of information about your heart rate, breathing, and skin temperature to recognize stress response symptoms is known as biofeedback. This technique was developed by Gary Schwartz at Harvard University. It involves using electronic equipment to measure a person's neuromuscular and autonomic activity, with feedback provided through visual or auditory signals. The idea is that individuals can develop strategies to gain some level of voluntary control over normally involuntary bodily processes. Biofeedback has been applied successfully to treat issues like tension headaches, high blood pressure, asthma, and phobias.
