Correct option is B
Biofeedback is a technique where individuals are given real-time information (feedback) about physiological processes (heart rate, muscle tension, skin temperature, etc.) and learn to consciously control/alter these processes.
Information Booster:
1. Common biofeedback modalities: EMG (muscle), EEG (brainwave), and thermal (skin temperature) biofeedback.
2. Widely used for stress management, chronic pain, and anxiety disorders.
3. Unlike simple relaxation, biofeedback provides objective, measurable data to the individual.
4. It works on principles of operant conditioning — the person learns through feedback-based reinforcement.
