What is the name of the channel that separates Cayman Brac from Little Cayman?

The channel that separates Cayman Brac from Little Cayman is known as the Bogue. This channel is a vital geographic feature that connects these two islands and influences local marine and ecological systems. The Bogue serves as a navigation route for boats and also contributes to the diverse marine biodiversity found in the area. Understanding this separation between islands is important as it reflects the geological formation of the entire Cayman Islands group and highlights aspects of their cultural and historical development related to fishing and navigation. This knowledge enhances the appreciation of the islands' geography and the interactions between their ecosystems.

The other options represent different bodies of water that are not relevant to the separation between Cayman Brac and Little Cayman, which is why they do not represent the correct answer in this context.
