In illustration D045NG below, a green-and-red banded daymark, with the uppermost band green, will have which of the following shapes?
AI Explanation
The correct answer is A.
A green-and-red banded daymark with the uppermost band green will have a triangular shape, as shown in option A. This is based on the U.S. Aids to Navigation System, which specifies that green-and-red banded daymarks with the uppermost band green indicate the shape of an isosceles triangle.
The other options, B, C, and D, do not match the shape requirement for this type of daymark and are therefore incorrect.
