Entering from sea, a daymark on the port side of the channel would be indicated on a chart by a _______________.

A green square with the letter G
B white triangle with the letters RG
C white square with the letters GR
D red triangle with the letter R
AI Explanation

The correct answer is A) green square with the letter G. A daymark on the port side of a channel is indicated on a chart by a green square with the letter G. This is in accordance with the United States Aids to Navigation System, which uses specific shapes and colors to mark the edges of navigable channels. A green square with the letter G specifically denotes a daymark on the port (left) side of the channel when entering from the sea. The other options are incorrect because they do not match the standard chart symbology for a port-hand daymark. B, C, and D represent different types of daymarks or navigation aids that would be used in different locations or contexts.
