Concept:A paradox is a statement that appears contradictory but reveals a deeper truth.
Explanation:In Okimba Launko's poem "End of War", the central device is paradox.
The poet uses statements that seem to contradict themselves on the surface.
For instance, the poem says, "a war only ends / when another war begins".
This line seems illogical because an end should not cause a new beginning.
Yet it suggests a cycle: every peace settlement can create new tensions that lead to another conflict.
That hidden truth makes the statement a paradox.
Antithesis and oxymoron are related but different devices.
Antithesis places opposite ideas side by side in balanced structures.
An oxymoron combines two contradictory words in one phrase.
Onomatopoeia uses words that imitate sounds.
Here, the whole idea is built on self-contradictory statements, so paradox is the dominant device.
Answer:C. paradox
