Answer
Hi, the correct answer is option {B} to assert that the speaker has a lot left to accomplish
Step-by-step explanation
This is the fourth stanza of the poem and the phrase has an important literal meaning. The phrase states that the speaker is traveling and will need to cover some distance before reaching his home. The meaning is symbolically from the word “sleep” which is used to suggest death and darkness. This line suggests a long journey ahead before the speaker could rest in eternal sleep of death. This is to mean that the speaker has many roles to fulfill before dying.
Hope this helps!
