Why element appears in widens missed ed beaux arts but is excluded in williams landscape with the fall of icarus

If the question means the difference betweent two poems 'Landscape with the fall of Icarus' by Williams and 'Musee des Beaux Arts' by Auden the answer is :

The element which appears in Auden's poem but is not present in the poem by Williams is the reference to a ship which was sailing close by. The poet infers that the sailors on the ship probably saw 'something amazing' i.e. a man falling from the sky. Nevertheless, they did absolutely nothing, they did not try to help but continued to sail calmly as they had probably something more important to do. Auden uses the image of the ship which sails calmly without paying attention to this dramatic fact, to pinpoint the indifference of the people.

i think the answer is b

because he was killed by the black arrow.
