The correct answer is B) Nominal range. The Light Lists published by the US Coast Guard express the intensity of a light in terms of its nominal range, which is the distance at which the light can be seen under average atmospheric conditions. The nominal range is the most commonly used measure of a light's intensity, as it provides a practical estimate of the distance at which the light can be reliably detected. The other options are not how light intensity is expressed in the Light Lists. Luminous range, meteorological range, and geographic range are not the standard measures used to indicate a light's intensity in the Coast Guard's navigational publications.
