Which buoy can be used to mark the center of a channel?

Explanation:
Safe Water Buoy marks the center of a channel because it indicates safe water in all directions. Placed along the channel centerline and at entrances, it reassures mariners that water is deep enough and protected on both sides, so they can pass on either side of the buoy. It’s typically a red-and-white vertical-striped buoy with a spherical topmark. Other marks have different purposes: an Isolated Danger Buoy signals a hazard with navigable water all around, Special Purpose marks denote yellow areas with specific restrictions, and Lateral buoys mark the sides of the channel.
