A (usually narrow) path in the water, marked by buoys, in which the water is deep enough to sail.

• A. Strait
• B. Inlet
• C. Channel
• D. Pass

Answer: (C)

A channel is a defined, navigable waterway that sailors use, often marked by buoys to show the safe path between deeper water and hazards. This matches the description of a usually narrow path in the water marked by buoys and deep enough to sail, providing a clear route for boats.

A strait connects two larger bodies of water and separates landmasses, not necessarily marked as a safe sailing path with buoys. An inlet is a waterway that leads inland toward shore, typically less about a marked sailing route and more about access to harbors. A pass is a navigable route through obstructions like reefs or shoals, but it’s more about getting through obstacles than a standard, marked deep-water channel.
