Both poems personalize a broad concept, such as spirituality or mortality. Option A is correct.
Emily Dickinson was one of the most important 19th century poets. “Some Keep The Sabbath Going To Church” illustrates her take on the concept of religion and all the norms it imposes. The centre of the poem is the day of Sabbath, or the day of rest in the Bible. She wrote the poem in the nineteenth century.
In "Because I Could Not Stop for Death" the persona of Dickinson's poem meets personified Death.
