The accurate conclusion based on the poem's structure is:
It is a litany poem in which the speaker, a father, uses second-person narration to give advice to his son.
This choice correctly identifies the poem as a litany, which is characterized by a repetitive structure that outlines a series of conditions or qualities, and it acknowledges the second-person perspective directed toward the speaker's son. The other options incorrectly categorize the poem’s form or fail to accurately capture its structure and intent.
