Correct answer: A. To study muscle activity
- A. To study muscle activity
- B. Determine class II malocclusion
- C. Determine the centric relation
- D. Determine the centric occlusion
Explanation
Electromyography records the electrical activity of skeletal muscle through surface or needle electrodes, helping assess muscle and motor-unit function. The other options are dental measurements rather than muscle electrical studies.
