Answer : B. It conveys the personal nature of the speaker's journey.
Step-by-step explanation:
This is an excerpt from Emily Dickinson's poem 'Because I Could Not Stop for Death'.
In the poem, Dickinson speaks of death as a positive experience, suggesting that it should not be feared. In the poem, the word Death is capitalized and thus personified. It takes a role of a gentle guide that accompanies the speaker on her journey to the afterlife.
When the speaker refers to her and Death as 'Ourselves', she strengthens the relationship between them, and makes it more personal. The term 'Ourselves' suggests that the two of them are now almost inseparable. In other words, the speaker's death is inevitable.
