Concept:The title must reflect the main setting and dominant atmosphere of the whole passage.
Explanation:The passage describes a stormy night at sea with rolling waves, mountains of water, caves, howling wind, and clamorous voices of the sea.
These details point directly to a scene of rough weather and darkness on the ocean.
Option A mentions a "savage struggle," but the passage focuses on the setting rather than a fight.
Options C and D describe only parts of the sea, not the full situation.
Therefore, the best title is the one that captures both the location and the weather condition.
Answer:B. At Sea on a Stormy Night.
