Final answer:
Electromyography (EMG) is the correct term for the display and recording of the electrical activity of the skeletal muscle, not to be confused with electrocardiography (ECG) which is for the heart.
Step-by-step explanation:
The correct answer to the question is b) Electromyography. Electromyography (EMG) is the technique used for displaying and recording the electrical activity of the skeletal muscle.
Unlike electrocardiography (ECG or EKG), which measures the electrical activity of the cardiac muscle, EMG measures the electrical activity of voluntary muscles.
Similarly, Electroencephalography (EEG) measures the electrical activity of the brain, and Electroluminescence refers to a material emitting light in response to the passage of an electric current or to a strong electric field. Therefore, for skeletal muscle activity, EMG is the appropriate term.
