INLAND ONLY Which is a characteristic of a "special flashing light"?

A It must be of the same character and construction as the masthead light.
B It is required for all vessels being pushed ahead as part of a composite unit.
C It must show through an arc of not less than 180° nor more than 225°.
D All of the above
AI Explanation

The correct answer is C) It must show through an arc of not less than 180° nor more than 225°. This is correct because the Inland Navigation Rules specify that a "special flashing light" must be visible through an arc of the horizon of not less than 180 degrees nor more than 225 degrees. This allows the light to be seen from multiple angles while the vessel is being pushed ahead as part of a composite unit. The other answer choices are incorrect because A) refers to the characteristics of a masthead light, B) is not a requirement for a special flashing light, and D) combines incorrect statements from the other choices.
