I don’t know if this is right but I think it is a metaphor if it isn’t I am sorry
The crew finally views the bird’s death as the cause of a b. drought. First they were angry at the mariner because they thought that the bird brought the breeze, then they congratulated the mariner because they said it brought mist and fog. Finally when they reach a calm sea and there is water everywhere but there is none to drink they blame the mariner for this and hang the bird's corpse around the mariner's neck.
I'm not 100% sure but I believe the answer is B.
