What is NOT a basic shiphandling rule for navigating in ice concentrations on the Great Lakes?

A Keep moving - even very slowly, but keep moving.
B Transit ice along pressure ridges when possible.
C Work with the ice movement, not against.
D Excessive speed means ice damage.
AI Explanation

The correct answer is B) Transit ice along pressure ridges when possible. The reasoning behind this is that pressure ridges are typically the thinnest and weakest parts of the ice, so navigating along them can minimize the risk of ice damage to the vessel. In contrast, the other options are not necessarily the best practices for navigating in ice concentrations. Option A (keep moving) may not always be feasible or advisable, option C (work with the ice movement) can be risky if the ice is unpredictable, and option D (excessive speed means ice damage) is a general principle that does not specifically address the optimal path through the ice.
