This line is used to build tension in the poem, and is later used to describe the captain's death, upon which the speaker mourns and anguishes. The reason why I DON'T THINK that it is B is because the anguihing is not in the moment of the events occuring when the refrain "Follen cold and dead" is stated. It is certainly not C or D, but it could be B. Take a gamble, but I think that it is A beuase of what I stated above.
