What is the approximate geographic range of Fenwick Island Light, Delaware, if your height of eye is 37 feet (11.6 meters)? Refer to "Reprints from the LIGHT LISTS AND COAST PILOTS".

Correct Answer: Option B — 17.8 nm

Geographic range is the distance at which a light can be seen based on the curvature of the earth. Using the formula 1.17 * (sqrt(Height of Eye) + sqrt(Height of Light)), and referencing the specific height of Fenwick Island Light, the calculation results in approximately 17.8 nautical miles.
