The finger is an optimal location due to the abundant blood vessels, making it easier to accurately measure oxygen levels. Clipping the sensor on the neck (A), stomach (C), or lower arm (D) would not provide accurate readings as these areas have less blood flow and are not suitable for accurate oxygen saturation measurements.
