Tibbetts Point Light, at the head of the St. Lawrence River, is shown from a _____ on the point?

Tibbetts Point Light is characterized by a white conical tower, which is a common design for lighthouses due to its aerodynamic shape that helps to resist wind and weather conditions while providing a distinctive visual marker for navigation. The conical shape is more stable than other forms, making it an effective choice for a lighthouse positioned at the entrance to the St. Lawrence River. This design also aids in the visual identification of the lighthouse from various angles and distances, which is crucial for mariners navigating through the waters. The use of white paint further enhances its visibility against the landscape and typical weather conditions.

The other choices reflect different lighthouse designs that do not apply to Tibbetts Point Light, thus confirming the uniqueness of the conical tower design in this context.
