I am honestly not sure because your options are confusing. The poet says in the last stanza that he doesn't want to take the form of anything natural - he wants to be made of gold, but not become a god, but rather a bird. He would like to be made into a golden bird and sing to the people around him. So I'm not sure what you should pick - he doesn't want to become a god, but rather a bird, but there is no mention of mechanics in the poem.
