Concept:A paradox is a statement that appears self-contradictory or impossible but reveals a meaningful truth when understood deeply.
Explanation:The line "The Child is father of the Man" seems logically impossible because a child cannot literally be the father of an adult.
However, the poet means that a person's childhood experiences shape and influence the adult he or she later becomes.
This is not a literal relationship; it is a figurative way to show cause and effect across time.
Therefore, the apparent contradiction contains a deeper truth.
Other options do not apply: synecdoche uses a part to represent the whole, apostrophe addresses an absent person, and metonymy substitutes a related term.
The device used here is clearly a paradox.
Answer:D. paradox
