Please answer by selecting exactly one option: A, B, C, or D.\n\nQuestion: What is the main purpose of the international 10-20 system?\nA. To standardize electrode quality using fixed impedance thresholds.\nB. To calibrate amplifiers using 10 Hz and 20 Hz signals.\nC. To ensure every cerebral lobe has exactly the same number of electrodes.\nD. To standardize scalp electrode locations using fixed proportional distances."
