Answer:
B). That his body will become part of the earth.
Step-by-step explanation:
'Song of Myself' is illustrated as one of the most acknowledged poems from his collection "Leaves of Grass". The poem celebrates 'individuality' (acknowledgment of self) and reflects the idea of 'transient' nature of human life. The poet describes the idea of the intermingling of the individual self with the 'universal self' and hopes for a mystical union with the almighty.
As per the question, in the given lines the poet suggests that 'his body will become a part of the earth' reflective of brevity of life(as reflected by 'I bequeath myself to the dirt') and thus, he anticipates a spiritual union of his self with the supreme authority(God). Therefore, option B is the correct answer.
