AI Explanation
The correct answer is C) the least depth within the limits of the channel which restricts the navigation.
The term "controlling depth" refers to the shallowest depth within a navigable waterway that limits the draft or maximum depth of vessels that can safely transit the area. This is the critical factor in determining the maximum size and load capacity of ships that can navigate a particular channel or body of water. The other answer choices do not accurately capture the definition of controlling depth as it applies to maritime navigation on the Great Lakes.
