Referring to the line given above I think about the first option as It explicitly describes the water at night.
The correct answer is: It explicitly describes the water at night.
Explanation: We are able to rule out the other options because there is no mentioning of people being fearful, or any hint of entries or doors. Also, it couldn't be implying "a vast and dangerous storm" because the text describes the world as "slumbrous", which describes the waters and the world as sleepy and peaceful.
